FAQ of Head Protection

HDPE (High Density Polyethylene) is generally used to manufacture general industrial safety helmets. The HDPE granule is a synthetic resin and plastics, selected for their good low temperature toughness. It has properties of good strength, superior processing performance, excellent impact resistance & environmental stress crack resistance. ABS (Acrylonitrile butadiene styrene), a common thermoplastic material used to manufacture helmet, with better impact resistance, toughness and lighter than HDPE. Helmets are often manufactured by reinforced fiberglass (FRP) for working in heat regions. There are helmets which are manufactured by Polycarbonate also.

In case of an impact, the force is transmitted/ distributed from the shell to the cradle and its points attached. This minimizes the impact of force on the user’s head; these points work as absorb the shock. 4 point or 6 point or 8 points helmets work effectively.

The general industrial safety helmets are certified for protection of the head from anything falling from overhead, like potential fall of material, tools, etc. from above. This is not ideal to be used while riding a bike.

The working life of helmet depends on the maintenance of the helmet. If polyester fibers get exposed for 300 days (in a year) for approximate 8-10 hours in a day, it can with stand 67% – 75% of their strength as compared to day 1. So there is a clear degradation of helmets. It is recommended that working life of helmet is 1 year.

Helmet have a shelf life of up to 3-5 years, when stored in ideal conditions away from direct sunlight and humidity. Excessive wear and tear can considerably reduce the lifespan of the product.

The helmet is personal protective equipment. It should be used till as long as there are no visible signs of wear or damage to any part of the helmet. It should be rejected after 1 year of use (Though the rejection based on criteria like working hours, ambient weather and exposition to sunlight)

It is advised user to inspects the helmet before using every time.

  • Inspect the shell for any signs of crack, deformation, burns or break.
  • Inspect the cradle for any signs of cut or damage, points of connection with the shell etc.
  • Inspect the ratchet or chin strap adjustment for its proper working.
