What are the elements of a respirator
program?
Where do I go for help?

Only applies if required by the label
◦ Requirements are normally found in the Personal
Protective Equipment section
and
◦ Crop specific information
◦ Other states may have specific regulations
◦ Respirators may be required for other tasks such as
welding, grinding, painting
 Respirator selection requires knowledge of the
exposure characteristics


Air Purifying Respirators

Air Supplying Respirators



All respirators must conform to NIOSH
certification
All Respirators must be maintained to the
level of the NIOSH certification
Altering respirator voids NIOSH Certification

Approximately 300 NIOSH
respirator certifications are issued
each year



90 manufacturers
102 manufacturing sites
18 countries

Follow the label

Type of application

Identify location

The respirator user
◦ Fumigation
◦ Air blaster
◦ Green house
◦ Inside vs outside
◦
◦
◦
◦
Beards
Size
Facial structure
Glasses
Don’t forget government inspectors!!

Two primary
types of filtering
media
◦ Dusts and Mists
◦ Gases and vapors





Purple (Magenta) – any particulate including
oil mist 99.97% efficient
Orange – Mercury Vapor/Chlorine gas
Black – Organic vapors (solvents and certain
pesticides
Green - Ammonia
Yellow – Organic Vapor and Acid Gas

What do these numbers mean?
◦ N ~ Not resistant to oil
◦ R ~ Oil resistant
◦ P ~ Oil Proof
◦ 95, 99 or 100 (99.97)
 Filter efficiency
NOT EFFICIENT!!!!!
NOT NIOSH APPROVED!!!!!!
QUIZ!!!!!
QUIZ!!!!!
Ref. 1910.134


Determined by multiplying the assigned
protection fact by the OSHA permissible
exposure level
Example:
◦ Exposure to unregulated dusts (PNOR)
 OSHA PEL = 10 mg/m3
 ½ face Air Purifying Respirator (APR) = Assigned
Protection Factor (APF) = 10
 Maximum Use Concentration (MUC) of 100 mg/m3

Select a program administrator
Choose the correct respirators
Provide medical evaluations
Fit test employees to selected respirators
Training on how to use respirators properly
Cleaning and maintenance
Cartridge change out schedules
Periodic program review

Medical Evaluations

Fit Testing
◦ Questionnaire (confidential)
◦ Reviewed by an Occupational Medical Practitioner
◦ Possible follow up examinations
◦ Protocols described in Appendix A 29CFR1910.134
◦ Two Types of fit testing
 Qualitative
 Quantitative

User Fit Check

1910.134 Appendix B-2 Cleaning Procedures

Sole user - cleaned as necessary

When Respirators are shared – after each use

Respirator inspection/replacement

Stored in a clean, sealed container
◦ Stored with cartridges?

Cartridges need to be change when an
employee experiences
◦ Breakthrough
 Smell
 Taste
◦ According to manufacture guidelines
◦ End of work shift
 Time of spraying operations not end of day
Only when respirators are required
By the label
