FOR USE IN NANOTECHNOLOGY ENVIRONMENT: OSHA recommends the use of HEPA filters or the equivalent
NIOSH 42 CFR 84 particulate filters (N100, R100 or P100) for protection from exposure to particles created during
nanotechnology processes. P3 is the equivalent per the AS/NZS and NBR Standards. Nano particles are defined as
matter between approximately 1 and 100 nanometers (nm). Air-purifying respirators reduce, but will not completely
eliminate, exposure to these contaminants. Because of their extremely small size, nano particles may enter the
breathing zone from any minute opening in the facepiece where other particles would not be able to enter. Use of
powered air-purifying respirators or supplied air respirators
4.
Immediately leave work area and remove respirator if:
Breathing becomes difficult;
You become dizzy or disoriented;
You smell, taste or otherwise sense contaminants; or
Your respirator is damaged.
5.
This respirator will not protect exposed areas of face or body from gases, vapors or airborne particles that can
irritate, burn or be absorbed through your skin. You must wear hand and/or body protection.
6.
Do not alter or modify this device in any way. Any alterations or modifications, including painting, affixing labels or
using unapproved replacement parts can reduce protection and expose the user to the risk of illness, injury or death.
HEALTH LIMITATIONS
You should be certified medically fit prior to using this respirator. In addition there are both physiological and psychological
limitations which should be considered before using respirators. They include, but are not limited to:
a)
Emphysema
b)
Chronic obstructive pulmonary disease
c)
Bronchial asthma
d)
X-ray evidence of pneumoconiosis
e)
Evidence of reduced pulmonary function
f)
Coronary artery disease
g)
Severe or progressive hypertension
would provide better protection against nano particles.
