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???

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

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
