Suction air line devices are not to be used together with respiratory helmets or hoods. They are normally used in conjunction with fuU-face masks. 

Respiratory helmets and hoods are very often used in combination with compressed air respirators. The technical requirements are documented in EN 14594 [6-71]. In the case of an increased air demand the regulation of the air volume...

Protect yourself from places and situations that are unsafe by immediately walking away or wearing an MCS mask, a half- or full-face respiratory mask, or by wearing a helmet with a portable air purifier. See entry 274 for more information. 

Surgical Recovery and Training After surgery, the monkeys are allowed to recover for at least three weeks prior to the start of the study. All monkeys are observed daily for signs of pain or distress and body weights are obtained at least weekly. All monkeys should be acclimated to handling, chair restraint, and the helmet used for respiratory measurements on at least 3 occasions prior to the start of each study. In addition, prior to implantation of the telemetry device, each monkey should be acclimated to the restraint chair and helmet for approximately 60 minutes on at least six occasions to ensure that the animals have the appropriate temperament. 

PERSONAL PROTECTION use asbestos protective clothing and face protection flame-resistant gloves are also recommended, as well as flame retardant jackets and pants use insulated footwear and safety shoes wear protective helmets and vented safety goggles workers should be supplied with appropriate respiratory equipment.

The castings are suspended on a monorail and move batch wise through the blasting cabin. For smaller pieces, a specific moving belt is used. Big pieces are blasted manually, using a lance in an enclosed cabin. In this case, personal safety measures are very important. A helmet with a dust mask and respiratory equipment are required.

Helmet means a rigid respiratory inlet covering that also provides head protection against impact and penetration. 

Respiratory inlet covering means that portion ofa respirator that forms the protective barrier between the user s respiratory tract and an air-purifying device orbreathing air source, or both. It may be a facepiece, helmet, hood, suit, or a mouthpiece respirator with nose clamp. 

Experience Industrial Respiratory Protection for welding that provides a cleaner and MORE PRODUCTIVE work environment. Our Powered Air Purifying Respirator (PAPR) with the 9400i Titanium helmet provides the ULTIMATE IN VERSATILITY for welding, grinding and respiratory protection. 

Use personal protective equipment — Engineering controls are not always feasible or may not provide enough protection. That s where respiratory protection comes into play. An abrasive-blasting respirator must be NIOSH-approved and cover your head, neck, and shorilders to protect you from rebounding abrasive. In addition, other personal protective equipment, such as hearing protection, eye and face protection, helmet, leather gloves, safety shoes or boots, and fall protection may be needed. 

The types of PPE have different functions, including hearing protection, eye protection, respiratory protection, protection of the skin, and general protection in the form of protective clothing, and safety helmets, harnesses and lifelines. Hearing protection was discussed in the previous section. 

The operators use personal protective equipment, such as safety helmet, safety boots, eye protection, ear protectors, respiratory equipment, and safety belts. Instructions, procedures, training and easy access to the equipment aim to promote this barrier .
