Hazmat suits - Chemical suits

Hazmat suits - also called chemical suits - are used to protect workers against dangerous substances in liquid or gaseous form. Choosing the right protection for each work situation can seem like a complicated task given the many available options.

First of all, it is necessary to assess the exact content of the chemical risks involved: bacteriological or chemical substances, solid, liquid or gas. Depending on their impermeability, chemical protective clothing is classified into 6 performance categories ranging from 1 for the most gas-tight to 6 for the least efficient.

Categories 1 and 2 are hazmat combinations of “diving suits” types and are particularly suitable for classified sites with high chemical risks. Types 3 and 4 (intermediate protection) are more often used in the petrochemical and chemical industries. Type 5 coveralls protect against air-carried solid particles (toxic dust) and can therefore be used for asbestos removal or during dusting operations in agricultural environments.

Hazmat suit - chemical suits classification

  • Type 1: Ventilated or non-ventilated gas-tight chemical protection against liquid chemicals, liquid aerosols and solid particles (EN 943-1)
    - 1a : OC-SCBA (open circuit self-contained breathing apparatus) worn inside the suit for maximum safety
    - 1b : SCBA worn outside the suit
    - 1c : Breathing air by positive pressure supplied air respirator system
  • Type 2: Ventilated or non-ventilated chemical protection NOT gas-tight against liquid chemicals, liquid aerosols and solid particles (EN 943-1)
  • Type 3: Liquid-tight protection (EN14605 standard)
  • Type 4: Spray-tight protection (EN14605 standard)
  • Type 5: Protection against solid particles suspended in the air (EN13982-1)
  • Type 6: Limited protection against non-hazardous liquid chemicals (EN13034)

Dräger hazmat suits

Dräger offers a wide range of chemical suits for many industrial applications ranging from decanting, cleaning and maintenance operations to emergency response.

  • Very diverse range of protective clothing: from a simple disposable hazmat suit to full protection, high resistance, reusable gear
  • High wearing comfort thanks to integrated ventilation systems for gas-tight chemical protective clothing
  • Wide range of accessories (protective boots and gloves, ventilation systems)

Maintenance & periodic control of chemical combinations

Chemical protection suits are class 3 personal protective equipment. They are therefore subject to an annual periodic inspection like all class 3 PPE. This periodic check includes a tightness check of the suit and of the valves on the test bench. control. For reusable versions, this full inspection should be performed annually for 10 years.
