The Safety Boot® Guardrail System is currently manufactured and marketed in several countries across the globe. The Safety Boot® has been tested by third party engineering firms as exceeding United States Federal OSHA guardrail regulations, as well as fall protection and guardrail safety requirements in the Canadian Territories and the countries of Australia and New Zealand. Stress engineering report summary is shipped with every order to ensure that written documentation is readily available on-site in the event of an on-site OSHA or safety inspection. Temporary guardrails or some type of fall protection must be utilized whenever an unprotected edge is 6 feet or more.
