6.13 WELDING SAFETY
When electric arc or oxy-welding or cutting, assisting or viewing the weld, use the correct head shield or goggles and other protective clothing necessary to protect arms, legs and body parts from flying sparks, molten metal etc. Protective screens must be set in position to protect other employees and the public from arc flashes and metal sparks.

6.14 HOT ENAMEL & MOLTEN LEAD (working with)

• The body should be protected - wear long trousers and a long sleeved shirt or coat.
• Trousers to be work on the outside of the boots
• A protective skin barrier cream should be applied to the more exposed skin area before working with Hot Enamel
• Gauntlet type gloves should be work
• A full-face mask shall be worn to protect the eyes, face and lungs from fumes and possible splatter.
• Always add additional cold materials very carefully and slowly to the molten materials. Cold wet lead thrown into a molten pot will cause a violent explosion.
• All pipe and fitting surfaces must be clean and dry before hot enamel or molten lead is poured.
• Make sure there is a clear pathway with no obstacles between heating the furnace and the pouring site before carrying molten materials.

6.15 WORKING WITH LIVE GAS
On all occasions when working with live gas where the flow of gas can not be stopped or kept below safe limits, gas masks must be worn and there must be at least one other person with a gas mask readily available standing by to assist. If in doubt seek advice. Check your mask and your air supply each time you put it on.
Smoking matches and naked flames must never be permitted in the vicinity of escaping gas.
Display suitable warning signs on the job and, if necessary, have someone posted to warn those of the hazard. Bonding leads should be attached across the job while cutting to prevent ignition of escaping gas by electric sparking.
If working on plastic pipes with gas issuing or venting from them, wipe the pipe with a wet cloth then drape the cloth around the pipe near the gas source. Static electricity on plastic pipes, due to contact with hands and clothing can, and has, caused sparking and gas ignition.
Fire extinguishers shall be placed in a handy position on the side of the trench when working with live gas. Keep the job wet with water to reduce sparking from the picks, bars, chisels and hammers.
Electrically driven tools, motor vehicles and mechanical plant with internal combustion engines, are a source of ignition and must be kept clear of the gaseous atmosphere.

Remember - A fire needs three things to start I Fuel, II Oxygen, III a source for ignition. Make sure at least one of these is eliminated.
