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
Types of 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
NIOSH Certification
NIOSH Respirator Certifications
Approximately 300 NIOSH respirator certifications are issued each year
90 manufacturers 102 manufacturing sites 18 countries
Follow the label
Type of application◦ Fumigation◦ Air blaster◦ Green house
Identify location◦ Inside vs outside
The respirator user◦ Beards◦ Size◦ Facial structure◦ Glasses
Respirator Selection
Don’t forget government inspectors!!
Dusts/Mists vs. Gases/Vapors
Two primary types of filtering media
◦ Dusts and Mists
◦ Gases and vapors
Common cartridge colors used in Agricultures 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
N95? P100? R99? N100? N99? 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!!!!!!
Oil Proof (P)?Efficiency?Does it earn a rating from NIOSH of a P-100 respirator???
QUIZ!!!!!
Oil Proof (P)EfficiencyDoes it earn a rating from NIOSH of a P-100 respirator???
NO!!!!!!

QUIZ!!!!!
Ref. 1910.134
Assigned Protection Factors (APF)
Maximum Use Concentration (MUC) 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
Program Elements
Medical Evaluations◦ Questionnaire (confidential)◦ Reviewed by an Occupational Medical Practitioner◦ Possible follow up examinations
Fit Testing◦ Protocols described in Appendix A 29CFR1910.134◦ Two Types of fit testing
Qualitative Quantitative
User Fit Check
Medical Evaluation & Fit Testing
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?
Cleaning and Storage
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
WPS change out schedules
Only when respirators are requiredBy the label
