SECTION 4: Personal Protection

WARNING
Prior to welding check operation of the filter lens, if the lens does not darken DO NOT COMMENCE WELDING. If during
welding the filter does not darken IMMEDIATELY STOP WELDING.
The radiation from an electric arc during the welding process can seriously harm eyes and skin. It is essential that the following
precautions be taken:
When electric arc welding, it is a requirement to use a welding helmet or welding handshield that complies to a relevant standard.
Protective filter lenses are provided to reduce the intensity of radiation entering the eye thus filtering out harmful infra-red, ultra-
violet radiation and a percentage of the visible light. Such filter lenses are incorporated into this Welding Helmet. To prevent
damage to the filter lenses from molten or hard particles an additional hard clear glass or special plastic external cover lens is
provided. This cover lens should always be kept in place and replaced before the damage impairs your vision while welding.
!
WARNING
For machine disc cutting, scaling, grinding and machining of metals and the like, additional eyeshields or faceshields with
appropriate impact rating should be used. Refer to AS/NZS1336 for full details of the appropriate protection for industrial
applications.
!
WARNING
The indicated filter lens shade numbers are minimum. If any discomfort is felt, higher shade numbers should be selected.
Recognised standards for recommended practices for occupational eye protection include AS/NZS 1336 and EN 175.
Gloves should be flameproof gauntlet type to protect hands and wrists from heat burns and harmful radiations. They should
be kept dry and in good repair.
Protective clothing must protect the operator from burns, spatter and harmful radiation. Woollen clothing is preferable to cot-
ton because of its greater flame resistance. Clothing should be free from oil or grease. Wear leggings and spats to protect the
lower portion of the legs and to prevent slag and molten metal from falling into boots or shoes.
