MSA has been making products for the U.S. Military Services since World War I. Rated #1 by Time Magazine. Currently their products protect workers from potential hazards at sites involving chemicals, construction, fire, mining and manufacturing. Some U.S. customers have asked about the use of MSA's products for "domestic preparedness" (related to emergency response, fire service, and civil defense preparations for protection against possible chemical and biological attacks on the U.S.)

  • Please be aware that there is no filter that we are aware of that will protect the user 100% against contaminants.
  • Please be aware that respiratory and face protection is only part of the answer to complete safety from biological and chemical warfare. Full body protection may be necessary.

    WARNING! Follow all instructions carefully. Misuse of protective equipment or failure to follow the warnings and instructions can result in serious personal injury or death.
  • This gas mask does NOT contain a supply of oxygen. It removes or neutralizes contaminants from inhaled air and must be used only in areas where there is sufficient oxygen to sustain life.

  • This gas mask is designed to provide respiratory protection only. Since many chemical and biological agents can enter the body through the skin, a hood and protective suit, including gloves and shoe coverings may be necessary.
  • This gas mask is effective up to a specified concentration. Avoid exposure to high concentrations of agent.
  • Put on gas mask and protective clothing at first indication of the presence of a warfare agent. Follow warnings of local authorities, as the presence of a warfare agent may not be detectable by sight or smell.
  • Follow directions of local authorities regarding where to go to seek shelter. Absent these directions, seek a secure place indoors and away from contaminated areas.
  • Do NOT remove gas mask or protective clothing in contaminated area.
  • As instructed by local authorities (after agent dissipates or when safely away from contaminated area), decontaminate mask and clothing. Remove mask and clothing only after proper decontamination as instructed by local authorities.
