Title Effect of outdoor weathering on the effective life of forest industry safety helmets
Bibliographic information 3 Nov. 1999, Vol.25, No.1, p.51-58. Illus. 8 ref.
Abstract While numerous national and international laboratory-based trials have been undertaken to determine the effective life of forest industry safety helmets, little local knowledge exists about the impact of actual outdoor weathering elements on the effective life of such helmets. A study was undertaken to determine the impact of outdoor weathering, in particular ultraviolet and visible solar radiation, on the effective life of three models of plastic safety helmets currently in use in New Zealand forestry operations. A sample of each helmet model and colour were destructively tested in accordance with the appropriate helmet standard at three-month intervals. It was found that the effective life of helmets exposed to outdoor weathering ranged from 13.5 to 36 months. Helmet colour appeared to have little influence on helmet failure rates. It is recommended that plastic safety helmets used in forest operations be replaced after 12 months continual use.
