Safety in the workplace is fundamental, especially in industries where hazardous chemicals are handled. In this context, the ANSI Z358.1 standard has become the global standard for emergency showers and eyewashes. We will explore this important standard and its impact on industrial safety in detail.

What is the ANSI Z358.1 standard?

The ANSI Z358.1 standard is a standard developed by the American National Standards Institute (ANSI) in collaboration with the International Association of Safety Equipment Manufacturers (ISEA). This standard establishes the minimum requirements for the design, performance, installation, use, and maintenance of emergency showers and eyewashes.

Key aspects of the standard

Performance requirements

  • The standard specifies detailed criteria for the performance of these devices:
  • Emergency showers must provide a minimum flow rate of 75.7 liters per minute for at least 15 minutes.
  • Eyewashes must provide a minimum flow rate of 1.5 liters per minute for 15 minutes.
  • Water must be warm, between 16°C and 38°C, to avoid thermal shock and encourage prolonged rinsing.

Location and accessibility

  • Devices must be located within 10 seconds of distance from potential hazard areas.
  • The path to these devices must be free from obstacles.
  • They must be easily visible and well-lit.

Maintenance and testing

  • It is necessary to activate weekly the devices connected to the water network to ensure correct functioning.
  • Annual comprehensive inspections must be performed to verify compliance with the standard.

Importance and application

Although the ANSI Z358.1 standard is technically voluntary, it is widely recognized and used by regulatory agencies such as OSHA in the United States. In many countries, including Spain, it is considered a fundamental reference for the design and installation of safety equipment in industrial environments.

Benefits of complying with the standard

  • Improved safety : Guarantees a rapid and effective response in case of chemical emergencies.
  • Legal compliance : Helps companies comply with workplace safety regulations.
  • Risk reduction : Minimizes the potential for severe injuries in case of exposure to hazardous substances.
  • Standardization : Provides a uniform framework for the manufacture and installation of these devices.
