Safety code – Mechanical.
There are many mechanical hazards present in a factory. We have to be
extremely careful and behave appropriately to avert accidents. Read the
following tips and follow them without fail.
General.
- Always
maintain your work area clean and tidy. Do not allow substances like oil,
grease, etc to remain on the floor.
- After
completion of every job, clear the area without fail. Do not leave
anything (bolts, nuts, bearing wrappers, etc) on the work spot.
- Do
not run any equipment without appropriate safety guards for the rotating /
moving / reciprocating parts.
- Always
keep safety in mind while working and do not take any undue risks.
- Always
ask for clarification if you have doubts. Stop the work and do not proceed
further until your doubt gets cleared.
- Always
carry out the work by following the prescribed procedures. If you do not
know the procedure or the procedure is not available, ask the person who
allotted the work to you.
- Never
run in the shop floor. You can get toppled.
- Do not
walk over running conveyors however slow they are. Always use the over
bridges or appropriate crossing points to cross the same. If it is not
available, report it to your superior.
- Always
wear safety shoes.
- For
all practical purposes, you should consider any height above six feet as
dangerous.
- Use
appropriate personal protective equipment like safety belt when you work
at a height.
- Get
an approved work permit, from the concerned authority, before starting the
work at height.
- Use
ladders with all steps and in good working condition.
- If
there is a problem in the hand rail of a ladder, report it immediately to
the supervisor.
- While
climbing, climb one step at a time.
- While
working at a height, ensure that there is an observer at the floor level
watching you.
- Ensure
that the observer is capable of taking appropriate decisions in case of
any eventuality.
- Have
a proper support for you while working at height. This will allow you to
focus on the job without any concern.
- When
you work over asbestos cement roofs, always use a cat ladder to walk above
the sheets. The cat ladder should be of appropriate design suitable for
the roof you are working with. Do not run over the roof.
- Never
drop anything (like spanner, bolt, nut, etc) from the height while you are
working.
Arc welding.
- Do
not touch live electrical parts.
- Wear
dry and hole-free insulating gloves while welding.
- Take
special care while welding in damp areas; avoid it as far as possible.
- Confirm
that the body of the welding transformer is properly earthed before using
it.
- Use
correct sized metal clad plugs for connecting the welding transformer.
- Protect
the electrical cable from hot metal and sparks. Keep them free of oil,
grease and joints.
- Periodically
inspect the cabled for damages and insulation failures. Get the faults
rectified through authorized electrical personnel.
- Do
not use damaged, undersized cables.
- Do
not touch the electrode if you are in contact with the work or ground or
another electrode from a different machine.
- Maintain
the transformer in good condition. Repair or replace the damaged parts at
once.
- Keep
all the covers and enclosures in place.
- Clamp
the earth electrode to the work piece securely. Use insulated clamps.
- Do
not connect more than one electrode or work cable to any single terminal.
- Do
not touch hot parts bare handed. Use proper tools for the same.
- Welding,
chipping, and wire brushing cause sparks and flying metal. Wear safety
glasses / goggles to prevent mishaps.
- Always
use helmet with proper welding glass while welding.
- Don’t
breathe welding fumes as they can be hazardous to your health.
- While
working in a confined space wear an air-supplied respirator. Always have a
trained watch-person nearby.
- Use
protective screens or barriers to protect others from flash, glare, and
sparks. Warn others not to watch the arc.
- Welding
in closed containers such as paint cans, oil drums can cause them explode.
Do not weld in closed containers.
- Flying
sparks, hot work piece can cause fires and burns. Keep fire buckets and
fire extinguishers handy.
Gas cylinders.
- Gas cylinders
contain gas under high pressure. If damaged, it can explode. Handle them
carefully.
- Protect
gas cylinders from mechanical damage, excessive heat, open flames, sparks
and arcs.
- Always
store the cylinders in upright position and secure them properly.
- Never
drape a welding torch over gas cylinders.
- Never
allow a welding electrode to touch any cylinder.
- Never
weld on a pressurized cylinder. It will explode.
- Always
use correct size and correct quality regulators, hoses, fittings and
torches.
- Turn
your face away from the valve outlet when you open it.
- Always
place the protective cap above the valve, if it is not in use.
- Store
the cylinders in their respective marked places – empty and full in their
respective places.
- Do
not place the cylinders close to open flames and arcs.
- Once
the job is complete, shift the cylinder to its designated place. Do not
leave it where you worked.
- Do
not use damaged hoses. Get them changed immediately.
- At
the end of the day, roll the hoses properly and hand over it to the
in-charge.
- Do
not leave the hose or regulator in the cylinder while leaving at the end
of the day. Remove them and hand over to the in-charge.
Diesel engine & Diesel Generating (DG) sets.
- Fuel
can cause fire or explosion. After stopping the engine, allow it to cool
before carrying out any work involving fuel.
- Do
not allow fuel to spill out or leak. Clean up immediately.
- Keep
away from moving parts like fans, belts and rotors.
- Keep
all doors of the sound-proof enclosure, panels, covers, and guards closed
and securely in place.
- Keep
hands, hair, loose clothing, and tools away from moving parts.
- Don’t
open the radiator plug immediately after stopping the engine. Hot steam
will come out which can cause severe burns. Allow the water pump to run
continuously and observe the water temperature. When it comes down
reasonably (around 40 degree), you can safely open the radiator cover.
- Do
not allow tools to cause sparks while working in a battery.
- Stop
the engine before disconnecting the battery.
- Never
run the engine without battery in the circuit since this may prevent
protection circuit from functioning.
- Always
maintain good ventilation in the room.
- Do
not remove doors, covers or guards while the engine is ON.
