Protect your head – Protect your future
Helmet is one of the most important items of personal protective equipment used by workers for protection against head injuries which may be caused by falling objects in many industries, for example, mining, tunnelling, quarrying, ship building, construction projects and similar occupations.
Head injuries caused by falling objects are usually serious and sometimes fatal. This standard has been prepared for industrial safety helmets capable of providing adequate protection from falling objects and other hazards commonly met with in many industries. This second revision has been prepared so as to include all the amendments issued so far besides relaxing number of achoring points of cradle from eight to minimum four so that latest designs could also be covered in the revised version besides including the provision of ventilation holes.
In formulating this standard, the Sectional Committee has taken special care to avoid unnecessary restriction in the design of safety helmets. If any special hazards, such as chemicals, oils, are likely to be encountered, the requirements of standard should be supplemented by special requirements to afford protection against such hazard.
- Metal Parts
Helmets shall be in sizes 520, 530, 540, 550, 560, 570, 580, 590 and 600 mm.
These sizes may be generated out of one or more shells or one or more headbands. The size adjustment range shall be clearly marked on the helmet.
The mass of a complete helmet without attachments and with or without peak may not exceed 400 g. If the mass exceeds 400 g, this mass determined to the nearest 35 g shall be shown on a label attached to the helmet.
Helmets required for use in underground mines shall have no metal parts made from aluminium or magnesium or their alloys.
