TECHNICAL UPDATE
3M™ Airstream™Safety Helmet Service Life
Helmet Life
Briefly, the standard says “field tests have shown that generally, helmet shells have a life of atleast 3 years from the time of issue” (Section 3.4). Helmets in use should not be discoloured orweathered and have no obvious damage from impact or deterioration. Old or used helmetshells with any damage should not be reissued. Helmet harnesses should “be replaced at inter-vals no longer than 2 years” (Section 3.4).
There are no specific guidelines given in the Standard for a maximum shelf life before a newhelmet is issued. They should be stored away from sunlight, dirt and temperature extremes,before and after issue. There is obviously some point at which a stored helmet shell should notbe used, but this is not specified. If stored helmets are suspect due to long storage times (wesuggest a period of >5 years from manufacture), they can be re-tested for performance by theNSW Workcover TestSafe laboratories. This involves a destructive test that requires 3 helmets
from the same production batch and costs several hundred dollars to perform. Unless thereare a significant number of “old” shells from the same manufacturing batch involved, this cost isnormally prohibitive and any old and suspect helmet shells should be discarded.
In 2004, 3M Australia introduced reflective stripes to the range of Airstream helmets. Therewere two main reasons for this:
1. To improve the visibility and safety of workers in light and dark environments.2. To provide an indication of the age of the helmet shell and when it may need reas-
sessment of its condition.
Airstream products that currently use these stripes include:
Airstream AH6TM Airstream AH6HRM Airstream AH12 Number 12 headtop is incorporated in products such as the 3M™ Dustmaster™ DM12,
3M™ Jupiter™ JT12, 3M™ Airline AL12. Spare/replacement helmet shells for these various products
The service life of any industrial safety helmet is addressed in Australian Standard AS/NZS 1800-1998: Occupational protective helmets – Selection, care and use”.Section 3.4 specifically addresses the working life of compliant helmets. The 3M™ Airstream™ style helmet is tested to meet the performance requirements of thisstandard.
