Features and Advantages NBC Mask Set


Crudesco’s Mask Set is a complete package consisting of:

  • Crudesco’s NBC Gas Mask
  • Crudesco’s NBC Gas Canister
  • Special NBC Mask Bag.

These products are designed to protect e.g. police and military in atmospheres containing chemical agents, biological agents and radioactive dust.

Intended end users include also Fire Fighters, Emergency Medical Service Personnel, Hazardous Materials Response Personnel and other Emergency Response Teams.

Our NBC Gas Mask has a 40mm threaded connector accepting USA/Military, EN and NATO type thread canisters, and meets all permeation requirements for US Military masks.

The NBC Gas Canister meets the performance requirements of NATO and US Military specification as a Chemical and Biological Canister (US Army C2A1).



One of the main advantages of Crudesco’s NBC Gas Mask is its value and safety for end users. Military, Police and first responders who are faced with Tear Gas and other less friendly Chemicals that are used at incidents, demonstrations and other eventualities do not want to compromise on quality and safety. Same goes for military or special operations, which can cause unnecessary casualties if bad quality masks are used.

Our Siebe Gorman Gasmask is tested against nasty substances, has a special design and materials assuring a minimum of lens fogging, maximum comfort, hard-coated polycarbonate lens with a wide view and scratch resistance.

Test Kits can be provided to supervisors and trainers, allowing them to check the function of any suspect mask that may have been damaged at an incident or through natural wear and tear. Failure to do this could result in faulty product or malfunction during use at an incident.

Space training facilities are available in Malaysia where we can train supervisors and trainers in the correct use of the mask. Inside the dual story space training facility we have we can disperse heavy fogging substance, which is totally non-toxic and harmless to replicate a typical scenario the end user may encounter.

Upon request, information about the Canister types and service life, communication test results and other specificaton information can be send.

What is the service life of the Canisters?

The service life of gas and vapor Canisters depends on the type of hazard encountered, the concentration of that hazard and environmental factors such as heat and humidity. Our Canisters were tested to challenge very heavy concentrations. Example: service time is guaranteed in excess of 60 minutes for Mustard and Sarin, and more than 600 minutes for tear gas. Please request us for further details.

Should the Canister be replaced after training or a false alarm?

It is not recommended to re-use/opening Canister for following reasons:

  • The Canister will not loose any significant service life when the mask is used for training or if used during a false alarm as long as the seal is not broke.
  • The Canister is 100% leak tested at the factory.
  • The Canister was designed for single use emergency evacuations. If used in an emergency evacuation, the user could be at risk if the Canister was opened before. A special color coding on the Canister will start indicating the service life left once the seal is broken and Canister used.

Could contaminants get into the Canister limiting their service life?

Unless air is being pulled through the Canister (as in breathing), it will not pick up contaminants or moisture. Our Canisters were tested in the atmosphere for years with little measurable decline in service life.

Can our Gas Mask be used for escape from radiation?

Our Canister will protect you against radioactive particulates. No hood on the market will provide protection from radiation (i.e. Gamma and Beta Rays).

Will Crudesco’s NBC Gas Mask protect me if there is a fire?

Proper NBC Masks are not designed to protect the user for escape from fire. Smoke particles can rapidly clog gas mask filters, and filters with special chemicals are needed to protect against carbon monoxide and other gases that may occur in a fire. Most air-purifying escape respirators do not protect against these hazards.

Our Breathing Apparatus range includes products protecting from gasses occurring in a fire. Please contact us for more details.
