Type 1 Class E safety helmets may be compliant with legal and regulatory standards for head protection in specific industrial environments if they meet the requirements outlined in the Occupational Health and Safety Code. The employer must ensure that workers wear protective headwear appropriate to the hazards they face. For industrial rope access work where lateral impact is unlikely, either Type I or Type II helmets that adhere to ANSI Standard Z89.1-2003 are acceptable. [1]

Additionally, protective headwear must be equipped with a retention system that has at least 3 separate points of attachment to the helmet shell, including a chin strap, and must be secured according to the manufacturer's specifications. [1] [1]
