Review: How can pesticides enter the body?  Swallowing - When not stored in original containers: accidentally drinking pesticides stored in bottles. Splashing during mixing and loading. Eating residues on food.  Inhaling - Breathing in vapors or dust during mixing, loading, spraying. Breathing fumes at storage site.  Absorbing through the skin - During mixing, loading, spraying. From residues on plants after spraying. From residues on sprayer. From residues on clothing. During PPE removal.  Eyes - From splashing during mixing, rubbing eyes with contaminated hands or clothing.

 What are the two most common routes of entry in pesticide handlers? Dermal and inhalation  Which formulations absorb most rapidly through the skin? Ones that are oil-based Note: In Washington, 73% of pesticide handler exposures requiring a visit to the doctor are due to eye exposure

What parts of the body (skin) absorb pesticides most rapidly?  The ear canal  The head (forehead & scalp)  The armpits  The genital areas

Why should you wash your hands before you go to the bathroom?

Remember – For those that mix and load pesticides:  The hands - 85% of all exposure

Choose gloves based on solvents used in the pesticides, NOT on the pesticides themselves  Which pesticide formulations absorb most rapidly through the skin? EC? WP? S? F? Ones that are oil-based (EC & F)

Useful for glove selection

Sample PPE Section – Category G

EXHIBITION, DEMONSTRATION, AND DISCUSSION OF DIFFERENT TYPES OF PPE To protect against the four routes of exposure:  Skin  Eyes  Inhaling  Swallowing

GLOVES  Cotton? Leather? Latex? Nitrile? Other?  What are + and - of each?  What about liners?

BOOTS  Okay to wear leather/cloth if label simply says “shoes plus socks”?

PROTECTIVE EYEWEAR  What are the minimum WPS requirements for Protective eyewear?  When are your eyes most in danger, and when is it most important to wear protective eyewear?  How to deal with fogging up?

Stealth goggles – “Comfortable and resistant to fogging” (so say the folks from Washington State)

RESPIRATORS

PPE in Fukishima Washington Post, March 27, 2011 One subcontracted worker who laid cables for new electrical lines March 19 described chaotic conditions and lax supervision that made him nervous. Masataka Hishida said neither he nor the workers around him were given a dosimeter, a device used to measure one’s exposure to radiation. He was surprised that workers were not given special shoes; rather, they were told to put plastic bags over their street shoes. When he was trying on the gas mask for the first time, he said the supervisor told him and other subcontractors, “Listen carefully, I’m only going to say this one time” while explaining how to use it.

RESPIRATORS  What’s the difference between a TC-21C and a TC-23C?  TC-84A = dust/mist. TC-23C = organic vapors  TC-23C: When should you change organic vapor cartridges?  What’s the difference between a fit check and a fit test, and when should you do each one?  Beards, medical evaluations, and respiratory protection program

COMMON RESPIRATOR VIOLATIONS No Written Program No Medical Evaluations No Fit Testing Improper Storage Wearers Having Beards Cartridge Change Out

“THE AIR YOU BREATHE” Available from OR-OSHA’s Publications Department

Commonly used in Hood River “Unsealed Filters have to be replaced every six months, regardless of the amount of hours worked.”

PROTECTING THE REST OF YOUR SKIN  Pants, coats, coveralls, headgear, aprons, etc.

WHERE AND HOW SHOULD YOU STORE YOUR PPE?  CLEAN YOUR PPE AFTER EACH USE!  NEVER STORE PPE NEAR PESTICIDES!  NEVER STORE PPE NEAR REGULAR CLOTHES OR FOOD!

WARNING: If you wear PPE you are in danger of “HEAT STRESS”! HEAT STRESS:  The body’s response to the excessive loss of water and salt in sweat  Symptoms –Heavy sweating –Pale and tired –Nausea and vomiting –Headache, blurred vision –Dizziness and fainting –Clammy moist skin

Personal risk factors Diet –Sugar added drinks –Heavy food –Malnutrition Alcohol Nicotine Caffeine

What are the differences between Heat Stress and Organophosphate or Carbamate poisoning?  HEAT STRESS:  DRY membranes, LARGE pupils, FAST pulse  ORGANOPHOSPHATE & CARBAMATE POISONING:  WET membranes, PINPOINT pupils, SLOW pulse  Farm Safety Tip: Main_Page.html Main_Page.html

HEAT STRESS & OP/CARBAMATE POISONING HEAT STRESS Sweating Headache Fatigue Nausea Dry Membranes Fast Pulse Dilated Pupils CNS Depression OP & CARBAMATE Sweating Headache Fatigue Nausea Moist Membranes Slow Pulse Pinpoint Pupils CNS Depression

To prevent heat stress  Drink water frequently during the day  Spray during the coolest time of the day  Do not drink colas, coffee, or alcohol

Cooling Vest

Emergency treatment of Heat Stress  Get the person out of the heat  Take off outer clothing  Cool the body using any method: Spray mist of water (evaporative cooling), fan the person, ice packs at armpits and neck, etc.  Have the person sip water frequently

Signal Word Exercise Draw a line from the signal word to the statement that best describes the level of toxicity or hazard Signal Words Level of Toxicity or Hazard WARNING-AVISOExtremely Toxic/Hazardous CAUTION-PRECAUCION DANGER-PELIGRO DANGER POISON PELIGRO VENENO Extremely Hazardous (to eyes/skin) Moderately Toxic/Hazardous Least Toxic/Hazardous
