SAFE WORK PRACTICE PRINCIPLES
1. Introduction
These general guidelines are intended to assist the Contractor in the
development of safe work practices. Where the risk assessment indicates that a
particular hazard cannot be present, the precautions to control that hazard do not
apply. Remember that a favorable history does not guarantee absence of hazard
on this occasion.
2. Confined Space
“Confined Space”, in relation to a place of work, means a space of any volume
which a person may at any time enter or be allowed to be entered in which the
atmosphere is liable at any time to be oxygen deficient. This includes but not
limited to pipes, sewers, machineholes, tunnels, shafts, ducts, other similar
sewerage installations and etc.
The Contractor shall develop acceptable work practices and safe entry
procedures based on the guidelines provided hereunder and the AMC’s safety
code on safety precautions to be observed during sewer desilting / lining work.
3. Notification to Work in Confined Space
The Contractor shall obtain an entry permit from the Engineer for each occupancy
of any confined space. The Contractor shall furnish all required details in an
approved format to the Engineer for permission to work in confined space at least
24 hours prior to the entry. Where prolonged work is involved, the permit must be
renewed for each shift. An incident, which substantially alters the condition of a
confined space entry, requires immediate evacuation and reassessment of the
4. Air Quality and Ventilation
Contaminant control and effective ventilation are major factors influencing air
quality in a confined space. The ventilation must be adequate to clear pre-existing
contaminated air and maintain a respirable atmosphere during planned work. This
ventilation may be permanently installed or portable equipment used for this task.
For general ventilation, fresh air should be supplied to the workplace. Within the
sewer system this creates an environment, which displaces contaminated air in
the immediate vicinity.
Where a task generates atmospheric contaminants in a specific area e.g. use of
chemical such as polyester resin, adequate local exhaust ventilation should be
used to remove the contaminants. Where failure of the mechanical ventilation
system would result in deterioration of air quality, the controls must be clearly
tagged to prevent accidental interference and the ventilation system monitored
while the confined space is occupied. Self-Rescuers must be carried whenever
failure of the ventilation system or changes in the working environment can create
a contaminated atmosphere. The self-rescuer can be a self-contained breathing
apparatus, oxygen self-rescuer, or short duration self-contained breathing
apparatus, depending on the time taken to reach open air.
Note: Obtain occupational hygiene advice on the selection or performance of
ventilation system where this is not specified in the work practice or plant design.
Any regularly accessed confined space should be illuminated to AS 1680 or
equivalent with electrical installation to AS 3000 or equivalent. Portable lighting
may be used to supplement permanent lighting in the workplace. Temporary
mains powered lighting installed for a task must comply with the requirements of
AS 2865 or equivalent Indian Standards. Miners lamps, mounted on a safety
helmet may be used as an alternative to a hand held torch for personal
Unless portable lighting complies with AS 2380.7 or similar Indian Standard the
possibility of a flammable atmosphere must be eliminated by isolation, cleaning,
ventilation purging etc.
Where the confined space has been proclaimed as a flammable gas hazard area
to AS 2430 or similar standard all fixed and temporary electrical installation must
comply with AS 2381 or equivalent standard. Torches and portable lights must
comply with AS 2380.7 or equivalent standard.
Illumination standards are: -
General Lighting: - 40 lux minimum, equivalent to a poorly
lit room Stairway Lighting: - 80 lux minimum
Task Lighting :- 240 lux minimum (normal workshop requirements)
6. Equipment usage, Standards and Maintenance
All confined space safety equipment as proposed in this tender documents shall
also meet the established international labour safety standards and be of
appropriate designed capacity for the proposed usage at sites. The equipment
must be checked for visible damage and correct operation before each use.
Preventative maintenance must be performed by trained, and where necessary,
authorized persons at the intervals recommended by the equipment
manufacturers. The Contractor shall submit to the Engineer evidence of such
periodic check and maintenance of the equipment used for confined space entry
at every first week of the month.
7. Room to Work
When the constricted volume of a worksite prevents normal work postures and
tool movement, the need for special tools or frequent work rotation should be
8. Control of Flooding
When a confined space is normally liquid filled, accidental return to service must
be prevented by double isolation e.g. insertion of suitable blanking piece, plugging
with inflatable plugs, temporary coffer dams as a second isolation in a
machinehole or other effective means.
9. Flow Control
Where a sewer is entered while flowing, rapid increase in flow must be prevented
by use of stop logs, isolation of pumping stations, weather watch and other
means appropriate to the sewer catchments. Adequate communication with the
person responsible for flow diversion must be maintained for the duration of the
Where deep flowing water is present, use personal flotation devices. Safety
harness and lifeline and safety nets as appropriate to prevent drowning and
11. Fire and Explosion
Adequate precautions must be taken to minimize the risk of fire or explosion when
entering a confined space for any purpose.
12. Presence of Flammable Gas
The presence of flammable gas, flammable dust or the possibility of the presence
of airborne substances in flammable quantities may create a hazardous Area.
Care shall be taken by the authorized person to determine the presence of any
such flammable situation in the confined space before entry. Smoking or lighting
any cigarette or box matches in confined space shall be strictly prohibited. The
flammable gases of concern are methane, digester gas, vapours from flammable
liquid, and vapours from trade waste discharges.
13. Manual Handling of Tools, etc.
Safe system of work should be followed to protect against falls of persons or
objects and crush by moving or falling objects.
Reverberation within a confined space can increase noise levels, especially if
more than one person is working. Heavy duty hearing protection may be required.
15. Vermin / Leptospirosis
All persons working in confined spaces should be aware of the leptospirosis
hazard presented by the presence of vermin. The presence of cockroaches etc.
does NOT indicate that the atmosphere is free of danger to health.
16. Standby and Communication
A member of the confined space work team is allocated the task of maintaining
communication with the members inside the confined spaces. This task may be
rotated among the members of the team. The Standby person must be trained
and be physically capable of providing the assistance and life support in an
emergency and must have sufficient proficiency in Hindi, English, Urdu and
Punjabi languages to promptly communicate information by radio or telephone
While acting as stand-by, this person must not enter the confined space or leave
the vicinity unless relieved from this duty. A standby person is needed for all
confined space entries. The Safe System of Work must indicate the process for
communication from the confined space to the standby e.g. 2 way radio ‘man
down’ alarm line of sigh etc.
17. Fitness Assessment
An assessment of fitness, including cardiovascular and respiratory health, is
required to ensure that all persons entering confined spaces, or acting as the
stand-by person, can comply with the physical demands of the job, without risk to
18. Emergency Rescue and First Aid
No person shall enter any confined space, even in an emergency, without first
ensuring all safety requirements have been met. A safety emergency plan may
assist in a safe, speedy response in the event of an emergency.
All confined space work teams must be trained and equipped to sustain life and
be able to summon emergency help, provide first aid and assist emergency
service personnel, if requested.
Trained persons using supplied air breathing apparatus must only attempt rescue
of persons apparently overcome by toxic gases in a sewer or other confined
spaces. Stabilization of other injuries must be prioritized against the availability of
breathable air.
19. Gas Detector
The Contractor shall engage an authorized person for gas monitoring and
detection. This person shall be trained to operate and response test gas testing
equipment and is authorized by management to perform the necessary tests to
decide whether a category 2 or 3 confined space is fit to enter.
Gas testing can only be performed by persons trained in gas testing, using
equipment appropriate for the anticipated contaminants. This person can perform
other duties provided these do not conflict with the gas-testing task.
20. Specialist Gas Detector
This person has technical qualifications and acceptable training to operate and
response test gas testing equipment, including hydrocarbon detectors and
detector tubes and assesses portable ventilation systems. He is authorized by
management to carry out atmospheric testing to establish entry conditions for all
confined space categories, and to establish whether a Category 1 confined space
can be re-classified to a Category 2. He also performs tests to verify whether hot
work is permitted in gas hazard areas.
Where possible, cleaning should be performed without entry to the confined
space, even if only preliminary cleaning is possible.
Particular attention should be given to the probability of releasing hydrogen
sulphide when disturbing microbial active sludge and sediments, which have
accumulated in a confined space. Supplied air respiratory protection shall be worn
where such residues exist and effective ventilation cannot be guaranteed.
Continuous gas monitoring is required even when supplied air respirator
protection is used.
Hose couplings should be designed to resist accidental dislodging or loosening.
Both the operators and the standby person should be able to stop the flow of
cleaning material into the confined space.
Hydro jetting must be performed according to the relevant regulations. Where
chemical compound is used in within the confined space, the chemical compound
should be classed in the Material Safety Data Sheets as non-irritant to respiratory
system, eyes and skin. If this is not possible then appropriate respirator skin and
eye protection must be worn. Substance specific air monitoring may be required.
A visitor to a confined space is a person other than a contractor, who is not a
member of the Confined Space Work team. Visitors must be escorted and trained
or inducted in the necessary skills for that entry and shall sign an indemnity form
before entry into a confined space. No visitor shall be allowed to enter the
confined space without prior permission of Engineer.
23. Hazard Control
Hazards to be identified and controlled include but are not limited to access
mechanical and electrical isolation, flow isolation and control, drowning and
engulfment, last known contents, atmospheric contaminants, temperature
extremes, security and public access.
24. Air Quality Standard For Entry
The acceptable limits of some gases in confined spaces are:
Gas/Vapor Present Acceptable Limits
a. Oxygen Content (o) 19.5% to 23.5% by volume
b. Flammable Gas/Vapor 5% of Lower Explosive Level (LEL)
c. Hydrogen Sulphide (H2S) 5 ppm
d. Carbon Monoxide (CO) 10 ppm
25. Carbon Monoxide (CO)
Carbon monoxide is colorless, odorless, flammable and toxic. Its common
sources are fire, motor vehicle exhausts and cigarette smoke.
This gas is a chemical asphyxiant and is readily absorbed by the hemoglobin in
the blood. Then hemoglobin is unable to transport oxygen to the body tissues and
the body becomes oxygen starved. These effects are more pronounced with hard
work or for heavy smokers. Symptoms include headache (50-200ppm), nausea
(400ppm), irregular heartbeat (1200ppm). Collapse and death (2000ppm).
The entry permit limit is 10 Parts Per Million (ppm). Maximum with an IDLH value
of 1500 ppm. (IDLH-Immediately Dangerous to Life and Health)
Note: Some gas detecting machine sensors are cross sensitive, H2S being
detected by the CO cell and vice versa. Alarm by either sensor requires
evacuation and re-evaluation of the safe system of work.
26. Flammable Gas/Vapor
A gas or vapor that will burn when mixed with air in certain proportions and
The mixture, which contains the least amount of flammable gases that will
explode, is called the Lower Explosive Limit (LEL). The mixture, which contains
just enough Oxygen to let the flammable gas explode, is called the Upper
Explosive Limit (UEL). The flammable range varies for gases and vapors.
Many of these have toxic effects when inhaled and a Workplace Exposure
Standard has been issued to protect workers from these Gas/Vapor. The
Contractor shall obtain relevant Workplace Exposure Standard (WES) for use in
Gas / Vapour Flammable Range 5% LEL WES
in % (FOR ENTRY PERMIT
Butane 1.9 – 8.5 950 ppm 800 ppm
n-Hexane 1.2 – 6.9 600 ppm 50 ppm
Methane 5 – 15 2500 ppm Axphyxiant
Petrol 1.3 –6 650 ppm 900mg/cum
Trichloroethylene 12.5 – 90 6259 ppm 50 ppm
27. Hydrogen Sulphide (H2S)
Hydrogen Sulphide is a colourless, toxic and flammable gas, which usually has
the odour of rotten eggs. In sewerage systems it is usually derived from the action
of bacteria on the sulphur compounds in anaerobic or old sewage. A small
amount of sludge or slime in wet wells or sewers will release a lot of H2S when
After a few minutes exposure, the ability to smell hydrogen sulphide by a person
is lost and then hydrogen sulphide becomes more dangerous as its presence is
no longer obvious and the person could become an innocent victim.
It can sometimes be detected by odour at less than 0.1 ppm but can be readily
detected by odour at 4 ppm. More serious health effects include eye irritation (10
ppm), respiratory irritation (50 ppm), headache, nausea, dizziness (200 ppm),
collapse and death (700 ppm).
The entry permit limits is 5 parts Per Million (ppm), Maximum with an Immediately
Dangerous to Life and Health (IDLH) value of 300 ppm.
Some gas detecting machine sensors are cross sensitive, H2S being detected by
the CO cell and vice versa. Alarm by either sensor requires evacuation and re-
evaluation of the safe system of work.
28. Methane (CH4)
The most common flammable gas found in sewers is methane. This mainly
comes from gas pipe leaks in the city’s gas distribution system. It can also be
derived from the action of anaerobic bacteria on rotting material. However a range
of other flammable gases and vapours may be encountered. These include LPG,
petrol vapour and other solvents.
Digester gas, found in anaerobic sludge digesters on sewage treatment plants is
a flammable mixture of methane nitrogen and carbon dioxide.
Methane is a colourless, odourless gas. Although pure methane is slightly lighter
than air the relative density of methane / air mixture is similar to air entry permit
range. Methane is hazardous because of its flammability, i.e. between
concentrations of 5% to 15% in air, it may explode if an ignition source is present.
High concentrations of methane may result in oxygen deficiency. Injury or death
result from lack of oxygen not methane toxicity classifying methane as a simple
29. Oxygen Content (O2)
Fresh air contains 20.9% oxygen, equivalent to a partial pressure of
hectopascal of oxygen at sea level.
The readings obtained on a gas detection instrument in open air may vary
depending on instrument calibration and barometric pressure.
In a confined space, oxygen can be used up by bacteria in sewage or sludge,
rusting of iron fittings, burning (or welding) or displaced (pushed out) by other
Breathing of air, which contains reduced oxygen results in increasingly serious
health effects. These range from impaired coordination and faulty judgment (12-
16% O2) to collapse and rapid death (less 6% O2).
Increased oxygen readings can only come from instrument error or by leakage
from oxygen cylinders, liquid oxygen tank, etc. High oxygen levels greatly
increase fire hazards, fires burn fiercely; oily clothing and hair can catch fire
without an ignition source.
The entry permit levels are 19.5% to 23.5% by volume.
Parts per million (ppm)
Parts of gas or vapour per million parts of contaminated air by volume at 200C
and 1 bar pressure.
Parts of substance per 100 parts of air,
water etc. 1% = 10,000 P
31. Other Atmospheric Contaminants
Entry, unless wearing air supplies breathing apparatus is not permitted unless
atmosphere contaminants are below the relevant 8-hour time weighted average
(TWA) Workplace Exposure Standard. This limit applies for all entries including
brief exposures. Entry wearing breathing apparatus is only permitted where the
concentration of the contaminant is within the protection factor of the breathing
apparatus and below the IDLH (Immediately Dangerous to Life and Health) value.
32. Sewer Gases
Air in contact with live sewage contains gases released from the sewer. For safe
entry, contaminated air must be replaced with clean air by ventilation of the
confined space. The resulting atmosphere must be confirmed by gas testing.
Discharge of untreated wastes, e.g. hypochlorites, electroplating effluent, acids
may result in generation of chlorine, hydrogen cyanide and other harmful gases
some distance from the original discharge.
33. Confined Space Categorisation
The confined space category is a guide to developing a safe system of work. The
confined space category may change to a more stringent level as a result of
adverse environmental factors or work produces contaminants. Alternatively it
may change to a less restrictive category if appropriate engineering upgrades,
whether temporary or permanent, are implemented.
1.1 Category 1 – Confined Space
Entry allowed only if flammable gas is below 5% of L.E.L. and other gases are
within the protection factor of the respiratory protective equipment used.
Visibility must be adequate

If the Category 1 confined space is a chemical storage tank, it can be reclassified
to a Category 2 or 3-confined space when the specialist gas detector confirms
that the chemical has been cleared from the interior.
Sewer, wet wells etc can be reclassified by a specialist gas detector to a lesser
confined space only when an approved safe system of work is employed. This
safe system of work must provide for demonstrated control of airborne
contaminants and other hazards in the workplace, to provide conditions
equivalent to a Category
Hot work requires control of fire and explosion hazards and may require air
supplied breathing apparatus to control fumes irrespective of the confined space
category. A Hot word permit is required in addition to the normal entry permit.
1.2 Category 2 – Confined Space
Entry allowed only if all gases are within entry permit limits. Personal Safety
o Wear specified protective clothing for the hazards.
o Wear safety harness.
o Use lifeline where appropriate.
Respiratory Protection
o Test air quality prior to entry
o If air quality test fails, refuse entry until reason found and rectified, or
revert to Category 1 entry conditions.
o Ensure adequate ventilation
o Monitor air quality during entry.
o Carry oxygen self rescuer
Note: Standby person must have SCBA readily available.
Hot work requires control of fire and explosion hazards and may require air
supplied breathing apparatus to control fumes irrespective of the confined space
category. A Hot word permit is required in addition to the normal entry permit. A
hydrocarbon check by a “specialist gas detector” is required unless the
environment can be upgraded to Category 3 conditions

D3:- SAFETY PRECUATIONS TO BE OBSERVED DURING CLEANING,
DESLITING AND LINING WORK.
18. Special Direction to Tenderers
1.1 Precautionary measures to be taken be the contractor for the safety and
welfare of the labours connoted with desilting and lining work.
To begin with the work of desilting, initiall six consecutive machineholes are
to be opened, two on the up-stream and two on the down-stream side of
the two machineholes, on the actual stretch to be cleaned or desilted. The
machineholes should be kept open for one hour prior to the starting of
cleansing operations and should be so kept open during the whole duration
of cleaning operations. This to be done for allowing the combustible gases
to escape naturally. No lighted matchsticks should be thrown in the
machinehole. This may cause fire and explosions endangering the life of
the workmen and the pedestrians. This may also damage to the sewer and
other adjoining utility services, if any Jalis should be placed over all the
opened machineholes to prevent pedestrians etc. from falling in. tripod
stands with flags it should be written in white bold letters “Danger
Machinehole Open.”
1.2 When working at night, lantern fitted with red globe and lights shall be hung
from the tripod stand. Each machinehole kept open should be guarded by
one labourer or C.I. heavy cover with holes exactly fitting up to the fame
and capable of taking the load of lorry should be placed over the
machinehole, so that top of the cover is flush with the road surface. The
contractor without any extra cost shall provide the covers. The same should
be removed and replaced with regular machinehole cover when the work is
1.3 The contractor should keep sufficient number measurement rods. The
measurement rods shall be made out of solid bamboo/M.S. rod of sufficient
length fixed with M.S. flat 150 mm X 150 mm X 6 mm (6”X6” and ¼”) thick
at one end and fitted with point at other end, to take measurement of water
1.4 Machineholes shall be kept open for minimum one hour to allow foul gases
to escape and simultaneously there should be forced purging with the help
or an are blower to completely clean the air in the sewer.
1.5 Sewage levels shall be checked in the machineholes and the same should
not be more then 450 mm (18”).
1.6 Wet lead acetate paper shall be inserted in the machineholes which should
nit turn even light brown or black. If the lead acetate paper turns light brown
or black, then the machinehole shows the presence of Hydrogen Sulphide
Gas (H2S) and in that case this test shall be repeated after every ten
minutes till positive result is achieved. The sensitivity of lead acetate paper
should be ascertained to suit and detect the minimum allowable
concentration (MAC) for long-term exposure.
This paper should be held as low as possible in the machinehole
atmosphere. In spite or long waiting for about one and half hour, if he lead
acetate paper continues to show negative gas detector shall be used for half
an hour. Thereafter gas detector shall be used to check the presences of
gases and the worker shall be allowed only after it is confirmed that the
condition inside the machinehole is safe for man entry.
Whenever necessary, or where the sewer line is heavily silted or there are
chances of gas eruption, the person entering the machinehole shall be
provided with gas mask or breathing apparatus (respiratory system) and
hand blower or mechanical blower be used during the desilting operation. In
every case use of gas monitor in working condition is mandatory. In
additional to this, the conventional methods lie lead acetate paper test etc.
be done. The gas monitors should be accurately calibrated after regular
intervals to maintain their reliability.
After the lead acetate paper test, a lighted safety lamp shall be inserted in
the machinehole, which should burn smoothly. If not, it shows the presence
of Carbon monoxide (CO) and in that case precautionary measures as
stated in sub-pare (g) should be followed.
After the presence of combustible gases are ruled out the following further
tests is required to be carried out for the presence of oxygen.
A lighted naked candle placed at the center of the candle testing equipment
covered with glass on three sides should be lowered down slowly. If the
flame is extinguished or flickers, it indicates the presence of carbon
monoxide and or carbon dioxide. If it burns for not less than five minutes
uniformly, it indicates the presence of oxygen, which is required for
breathing for the workman working inside the machinehole.
19. Working Inside the Machinehole
After all these tests are carried out successfully, particular care should be
taken where sewer is heavily silted, the scum and sullage should thoroughly
be stirred and disturbed by means of long bamboos/ G.I. rod from the top of
the machinehole to allow entrapped gases within silt pockets to escape
before allowing the labourers to go down into the machinehole.
The depth of water should be measured and the labourer should be asked to
get down when the level of water is less then 450 mm (18”). Before the
labourer is allowed to get down inside the machinehole, he should be asked
to apply barrier creams all over the body as a precautionary measures to
safe guard against itching and burning sensation. Safety belt should be tied
around his waist and chest when the labourers are getting down, another
man at the top should hold the other end of the rope. Not less then two
people should be allowed to work inside the machinehole at a time.
If the labourers who are working inside the machinehole show slight
discomfort, they should be asked to come up or pulled up. The labourers
who are working inside the machinehole should give jerks every few minutes
to signify that everything is okay with them.
After getting satisfactory test result and after taking precautionary measures
as stated above, the worker shall be allowed to descend or enter in the
machinehole. The workers entering the machinehole shall be provided with
wadder suit, hand gloves protective head gears and head lamp. If the
wadder suits are not available the worker shall be provided with Barrier
Creams with germicide to be applied to their entire body to prevent harmful
effect due to contact with harmful bacteria and germs.
The worker entering the machinehole shall wear Harness belt around his
waist. In spite of the machinehole entry tests being carried out, there are
chances of eruption of poisonous gasses in the silt. If the worker finds any
difficulty in breathing initially or during the work then he should be taken out
immediately by means of harness belt. Where the sewer line is heavily silted
or there are chances of gas eruption, gas mask shall be used while entering
the machinehole and also during desilting.
On completion of the work all machineholes shall be checked and it should
be ascertained that the same are properly closed.
20. Safety (General)
Proper ventilation shall be maintained in the machinehole and sewer line
being desilted. Hand operated or mechanical blower should be preferable
used for half an hour to one hour before entering the sewer line even after
getting the safe working condition, while desilting sewer lines where
accumulation of silt is heavy. While the blowers shall be operated
continuously during the desilting of sewer lines which are heavily silted or
susceptible to gas generation.
While carrying out desisting, the sewer lines of man-entry size, the
contractors shall use blower during the entire period. This would not only
ensure safe condition but also ensure comfortable working condition for the
worker and would in turn increase his performance and output.
In some machinehole where sewage is falling over workman or causing
obstruction, plugging the upstream sewer will be allowed temporarily without
any charges, provided the Contractor ensures that the upstream sewer line
does not overflow. The plugs shall be removed immediately after the work
has been completed.
The Contractor shall, as far as possible, use mechanical process for
cleaning and desilting sewer lines and progressively minimise manual
process of desilting so that entry of workers in the sewers for purpose of
cleaning and desilting shall be avoided.
