IS 2925:2000 is the Indian Standard (BIS) for industrial safety helmets (bilingual). This standard prescribes the requirements regarding material, construction, workmanship, finish, and performance tests for industrial safety helmets. It ensures the helmets provide adequate protection against falling objects, impacts, electrical shocks, and flammability hazards.

Practical Notes
! Ensure the harness fits properly to maintain the mandatory minimum 30 mm clearance for effective shock absorption.
! Helmets subjected to a severe impact must be replaced immediately, even if no visible damage is present.
! Avoid painting or applying unapproved adhesives to the helmet shell, as solvents can significantly degrade the plastic's strength.

Frequently Asked Questions4
What is the minimum head clearance required inside the safety helmet?+
A minimum crown clearance of 30 mm must be maintained between the top of the head and the inside of the shell.
What is the maximum allowed transmitted force during a shock test?+
The maximum force transmitted to the headform must not exceed 5.0 kN.
Are industrial safety helmets tested for electrical resistance?+
Yes, they are tested at 1200 V AC for 1 minute, and leakage current must not exceed 3 mA.
Can safety helmets be reused after a severe impact?+
No, helmets must be permanently discarded and replaced after any severe impact.
