SELECTING THE RIGHT FEATURES
AS/NZS 1715:1994 standard sets out the principles of respiratory protection and makes recommendations for the selection, use and maintenance of respirators for personal protection against atmospheres deficient in oxygen or against harmful substances.
P2 Disposable Respirators
P2 dust/mist and fume respirators with adjustable plastic nose clip and soft foam nosepiece for comfortable custom fit. P2 designated respirators provide protection against thermally generated fumes and smoke when, for example, welding; soldering; brazing; metal cutting or pouring.
Disposable Respirators with valve
The P2v valve makes breathing easier, cooler and also extends the life of the mask.
Disposable Respirator with Active Carbon
These respirators are covered with active carbon to pre-filter organic vapours, and feature an adjustable plastic nose clip and soft foam nosepiece for comfortable, custom fit. These respirators also contain active carbon, protecting against mechanically generated particulates and mists of sizes commonly encountered in industry, and mining dusts (i.e. Coal, copper, zinc, lead; dusts from fibreglass, asbestos, timber, cement). The valve adds comfort and helps to extend the longevity of the mask.
USE AND MAINTENANCE
Operational temperature range for use 0 to +50 degrees C Disposable respirators are not suitable for use in:
- – Oxygen deficient atmospheres (less than 18%)
- – Atmospheres immediately dangerous to life and health (IDLH) containing toxic gases or vapours
- – Areas where the particulate concentration exceeds 10 times the occupational exposure limit
- – Highly toxic atmospheres (refer to AS/NSZ1716)
How often should they be replaced?
Disposable respirators are designed to last throughout an 8 hour shift. However, the effectiveness of the respirator will deteriorate faster in hot, dusty, humid conditions or in the presence of oil and oil mists. Please note that respirators should not be cleaned or reused. Instead, replace the entire mask when shift ends or if the filter medium becomes clogged.
How should they be stored?
It is recommended to store the respirators at 20~30°C in a clean dry environment.
