Head protection

Employees shall wear non-conductive head protection wherever there is a danger of head injury from electric shock or burns due to an electrical explosion.

This time i want discuss about safety helmet or hard hat.This is very important PPE that we compulsory wearing when perform electrical job.

Safety helmet very important because it can protected we from serious head injury again mechanical impacts, falling objects, debris,electric shock and impact with other objects.

Hard hat colors can signify different roles on construction sites. For instance, white might signify supervisors or engineers, blue technical advisors, red safety inspectors, and yellow laborers.

General Specification Safety Helmet / Hard Hat


1)Resist penetration by objects

2) Complete with proper instructions explaining

3) Good absorb the shock

4) Water resistant

5) Slow burning

Type of  Hard Hat


  • Class A.

These helmets are for general service. They provide good impact protection but limited voltage protection. They are used mainly in mining, building construction, shipbuilding, lumbering, and manufacturing.

  • Class B.

Choose Class B helmets if your employees are engaged in electrical work. They protect against falling objects and high-voltage shock and burns.

  • Class C.

Designed for comfort, these light-weight helmets offer limited protection. They protect workers from bumping against fixed objects but do not protect against falling objects or electric shock.

Working at high

Designed for any high level and can protection for fall in impact.It suitable for working at high and it have special design and characteristic.

 

* Each kind of protective helmet is designed to protect against specific hazards. By completing the hazard assessment outlined above, you will identify the specific workplace hazards that pose a threat to your employee’s head.

How to kept hard hat in good condition?

Avoid :

  • Do not paint or clean your hard hat using cleaning chemical like thinner or etc.It can weaken the shell of the hard hat and may eliminate electrical resistance.
  • Refer the manufacturer information on the effects of paint and cleaning materials on their hard hats.
  • Do not apply new paint and stickers.It can hide a signs of deterioration in the hard hat shell.
  • Do not store or transport hard hats on the rear-window shelves of automobiles or otherwise in direct sunlight

How to clean the hard hat?

  • Immersing for one minute in hot (approximately 140o F, or 60o C) water and detergent,
  • Scrubbing, and Rinsing in clear hot water
  • Use a clean cloth

Standard for safety helmet

Hard Hat Impact Types

Type I Hard Hats

Type I hard hats are intended to reduce the force of impact resulting for a blow only to the top of the head. All hard hats, except bump caps, listed on the Cooper Safety website are Type I (top impact) hard hats.

Type II Hard Hats

Type II hard hats are intended to reduce the force of impact resulting from a blow which may be received off center or to the top of the head. A Type II hard hat typically is lined on the inside with thick high density foam.

Electrical Classes

Class G (General)

Class G hard hats are intended to reduce the danger of contact exposure to low voltage conductors. Test samples are proof tested at 2200 volts (phase to ground). However, this voltage is not intended as an indication of the voltage at which the hard hat protects the wearer. Please note: Class G hard hats were formerly known as Class A.

Class E (Electrical)

Class E hard hats are intended to reduce the danger of exposure to high voltage conductors. Test samples are proof-tested at 20,000 volts (phase to ground). However, this voltage is not intended as an indication of the voltage at which the helmet protects the wearer. Please note: Class E hard hats were formerly known as Class B.

Class C (Conductive)

Class C hard hats are not intended to provide protection against contact with electrical conductors.
