Respiratory devices materials

The amount of time they can safely work in an area contaminated with radioactive materials Equipment needed to protect ihem.seives from radiation and radioactive materials Types of respiratory devices needed to work in the contaminated area How to use radiation monitoring devices... 

In cases where respiratory devices are used to avoid exceeding occupational exposure limits, chemical protective suits are necessary. These are available for use against many different chemicals, and are made from various types of elastomer materials or coated fabrics. Most chemical protective suits enclose the whole body. In order to reduce any leaks, the protective boots are integrated. Normally one can choose from protective suits having fiiU face masks with a connector for a cartridge or an external compressed air breathing apparatus (Fig. 6.25 b), or with an... 

Protective devices are often used to prevent contact of chemicals with the respiratory tract, eyes, skin, and digestive system. Foulger states that a safety program should be designed to prevent or minimize contact of chemicals (or materials that are injurious to health) with the body respiratory protective devices, safety glasses and shields, impermeable clothing, gloves, shoes, and masks must be made available... 

Everyone should be familiarwith the location anduseofaUequipment in their laboratory area. As noted above, this includes means to initiate an evacuation (fire alarm pull stations, etc.), fire extinguishers, fire blankets, eyewash stations, deluge showers, first aid kits, spiU kit materials, respiratory protective devices, and any other materials normally kept in the area for emergency response. 

Many of the materials incorporated in respiratory medical devices do not directly contact the person using the device. Therefore, materials are not subject to the same biocompatibility constraints as are implantable or surface contact devices. There is a need, however, to be sure that materials are rugged enough to stand up to repeated use under sometimes fiantic circumstances. An endotracheal tube, for instance, must not fail during insertion into the trachea. In addition, materials in the air passage... 

A respiratory protection device that consists of a supply of respirable air, oxygen, or oxygen-generating material worn by the worker. It is designed for entry into and escape from atmospheres Immediately Dangerous to Life or Health (IDLH) or oxygen deficient. It is one of the highest levels of respiratory protection. Wearers carry the air supply on their back.
