28 Cards in this Set

  • Front
  • Back
Acute effect
Ilness or injury that appears immediately, or very soon after, exposure to pesticide (usually within 24 hours)
Chemical resistant
Able to prevent movement of pesticide through material during period of use
Concentrate
Pesticide with high percentage of active ingredient
Delayed effects
Illness that appears shortly, but usually more than 24-hours after exposure to pesticide
Diluent
Anything used to dilute pesticide
Exposure
Coming into contact with pesticide. Getting pesiticde on a surface or in or on an organism
HEPA (High-efficiency Particulate Air)
Filtration that must, as defined by law, capture 99.7% of all particles down to 0.3 micron -- about 240 times smaller than the width of a human hair
MSHA (Mine Safety and Health Administation)
Administers the provisions of the Federal Mine Safety and Health Act of 1977 (Mine Act) and enforces compliance with mandatory safety-and-health standards as a means to "eliminate" fatal accidents; to reduce frequency/severity of non-fatal accidents; to minimize health hazards; and to promote health/safety conditions in nation's mines
NIOSH (Nat'l Institute for Occupational Safety and Health)
Federal agency established by OSHA of 1970. Part of the Centers for Disease Control and Prevention. Responsible for conducting research, making recommendations for prevention of work-related illness and injuries.
OSHA (Occupational Safety and Health Administration)
Fed organization that oversees workplace safety
Personal Protective Equipment (PPE)
Devices and clothing worn to protect the human body
from contact with pesticides and its residue
What legal responsibility do you have for wearing the PPE that the label lists for your handling situation?
By law, you must wear AT LEAST the PPE listed on the label for the handling task you are performing. You are allowed to wear additional and/or more-protective PPE.
Define "chemical resistant."
Able to prevent movement of pesticide
through the material during the period of use
How can you tell when a material is not chemical-resistant to the pesticide being handled?
The material may change color; become, soft or spongy; swell or bubble up; dissolve or become like jelly; crack or develop holes; become stiff or brittle.
What factors determine how well your coverall will protect your body?
1. Fits loosely; there is a layer of air between it and the skin or inner clothing
2. Worn over another layer of clothing (adds layers and air space)
3. Tightly constructed seams and snug, overlapping closures that do not gap or easily unfastened
When should you wear chemical-resistant gloves? Why are they important?
Wear gloves any time you might get pesticides on your hands, except when the label states otherwise (some fumigants). The hands are the most likely route of exposure.
If you need to remove gloves during the handling activity, what steps should be taken to remove and put them them back on?
1. Wash gloves thoroughly before taking them off
2. Wash and dry hands before putting gloves back on
Why might pesticides get on your skin
even when wearing gloves and protective footwear?
1. The items may not resist the pesticide being handled;
2. they may not be in good condition;
3. or not properly cleaned or not replaced soon enough
When should protective headwear be worn? What type should be used?
When exposed from above, wear protective headgear to keep pesticides off head, neck, eyes, mouth, and face. Chemical-resistant hood; wide-brimmed hat. Plastic "safari" hats with plastic sweatbands a good choice.
When the label calls for "protective eyewear," what should be worn?
Goggles, face shield, or safety glasses with brow and side shields
What are the differences between these respirators?

1. Dust/mist-filtering
2. Vapor-removing
3. Air-suppling
1. Dust/mist-filtering: masks or cartridges that filter dust, mists, particles
2. Vapor-removing: uses cartridge or canister
3. Air-suppling: provides clean air from tank or from an uncontaminated area
What special hazards do fumigants pose to handlers?
1. Inhalation
2. Skin burns
The chemical-resistant gloves are reuseable, how often should they be routinely replaced? When should they be replaced immediately?
1. After 5-7 days of work
2. Wear, holes, tears, leaks
What should be done with coveralls that have highly toxic concentrate spilled on them?
Dispose. Can't be cleaned adequately.
How should you protect yourself when you launder your clothing?
1. Wear chemical-resistant gloves and apron, especially if handling items regularly or if items have been contaminated with highly toxic pesticides
2. Work in well-ventilated area; do not inhale steam from washer or dryer.
What should you do with your respirator between handling tasks?
Seal respirator in clean, airtight container; e.g., sturdy zip-lock bag.
If possible, put caps over cartridge or canister openings.
What should be done when you are through with your respirator for the day?
1. Discard masks, filters, respirators that can't be reused
2. Take off pre-filters, cartridges, canisters and discard. If reusable, after replacing caps, seal in airtight container (sturdy zip-lock bag)
3. Wash respirator body, faceplate, reusable filters. Soak 2+ minutes in mixture of 2 tablespoons chlorine bleach in gallon hot water. Rinse. Hang to dry.
4. Store respirator and associated items in airtight container in a protected area
How will you know when to replace masks, pre-filters, filters, canisters and cartridges?
1. Dust/mite masks, cartridges, pre-filters if breathing difficult -- usually after 8 hours of use
2. Vapor-removing canisters or cartridges immediately if pesticide smell, taste, irritation.
3. Service-life indicator; label time limit, otherwise after 8 hours of use.
