Safe Use of Acetylene Gas

TOOL BOX TALK MEETING TRAINING
Safe Storage of Acetylene Gas Cylinders
Store Acetylene gas cylinders in a
safe well ventilated area that is secure and lockable, when not in use. Ensure
the storage area is kept locked. Never store acetylene gas cylinders in
occupied buildings, unventilated rooms, underground rooms (cellars) or in areas
accessible to the employees without any approval.
Store Acetylene gas cylinders away
from heat and ignition sources, flammable or corrosive materials.
Cylinders should only be stored in
areas where water cannot accumulate as this can cause corrosion to the cylinder
base.
Ensure that cylinders are secured
upright.
CHEMICAL SAFETY HAZARDS & MSDS
Ensure the storage area is designated
“NO SMOKING” and that there are no other ignition sources in the area.
Ensure MSDS is displayed in the
storage area.
Rotate stock on a first in, first out
basis as good practice.
Ensure required fire protection is
provided in the storage area.
Ensure emergency contact numbers are displayed
legibly in the storage area.

Safe Use of Acetylene Gas
Only authorized employees allowed
working with Acetylene Gas
Before using cylinders ensure that employee
have been properly trained and are competent with the equipment being used.
When moving cylinders from the cylinder storage area to the place of work, ensure that the valve is closed and fitted with a protection cap or valve guard. Use a cylinder trolley. Never shift the cylinders without trolley.
Before commencing work, ensure the
work area is adequately ventilated, clean and that appropriate risk assessments
have been conducted.
Equipment shall be designed
specifically for acetylene (propane or oxygen equipment might not be suitable)
and shall be kept in good working condition and free from oil or grease.
ROAD SAFETY MONTH SAFETY RULES ON THE ROAD
Ensure flashback arrestors and check (non-return)
valves are installed.
Ensure availability of appropriate and
adequate fire extinguishers. It is strongly recommended that dry powder type
fire extinguishers are available close to or in the work area.
Do not use the cylinders in horizontal
position, Acetylene cylinders are designed to be used in the vertical position.
This helps to avoid solvent spitting experienced with some types of porous
material.
Flashback occurs when acetylene flow rate is lower than torch demand. Too high flow causes spitting, flame disturbance and reduces the effectiveness of flashback prevention devices.
If spitting continues the cylinder
should be removed from service, marked or labelled and returned to the
supplier.
Cylinders should always be secured ,
for example by means of retaining straps or chain, pallets or barriers, when in
use. Use with trolley always.
ARC FLASH HAZARDS AND PROPER PRECAUTIONS
Do NOT “crack” open the cylinder valve to blow out dust from the valve outlet as there is a risk of ignition. If necessary, clean the outlet valve with a lint free cloth before connecting the regulator.
When connected, ensure that the
regulator pressure is released and face away from the outlet before slowly opening
the cylinder valve.
Ensure that the equipment is leak
tested and purged of air before use.
Before use, check for gas leaks at
each connection with a suitable leak detection product.
Always treat the torch with care.
Never use the torch as a hammer.
