OSHA Regulations
The Occupational Safety and Health Administration (OSHA) sets forth regulations that are designed to protect workers from hazards in the workplace. Regarding footwear, OSHA mandates that employees must wear protective footwear when working in areas where there is a danger of foot injuries due to falling or rolling objects, or objects piercing the sole, and where such employee's feet are exposed to electrical hazards. OSHA's guidelines reference standards for protective footwear, which must comply with specific consensus standards.
ASTM Standards
The American Society for Testing and Materials (ASTM) provides standards that are widely followed for industrial safety footwear. ASTM F2412 and ASTM F2413 are the principal standards that describe the minimum requirements for the performance, design, testing, and classification of protective footwear. The standards cover various aspects such as impact and compression resistance, metatarsal protection, conductive properties, electric shock resistance, static dissipative properties, and protection from punctures.
ISO and EN Norms
The International Organization for Standardization (ISO) and the European Committee for Standardization (EN) also provide norms for safety footwear. ISO 20345 is a widely recognized standard that specifies basic and additional requirements for safety footwear used in general industrial environments. It categorizes safety footwear into different levels of protection including toe protection, midsole penetration resistance, and thermal risks. Similarly, EN ISO 20345 is a European standard that aligns with ISO 20345, ensuring a harmonized level of protection for safety footwear within the European Union.
