Advice for pesticide handlers and survivalists: Do not overestimate the power of a gas mask!

In studying the laws and regulations for pest control in the state of California, I came across a shocking pamphlet that made me worry for the safety of all those workers that have to spray volatile chemicals for a living, and even all those hairy mountain men that stockpile canned goods, weapons and, yes, gas masks, for the end of days. As a blogger, I am not encouraging or opposing this idea, but buying gas masks on line that are not fitted to your face and don’t accommodate any facial hair (if you have any), gives a person a false sense of security in the face of chemical exposure, so READ ON:

“IF I HAVE A MUSTACHE OR A BEARD.CAN I WEAR A RESPIRATOR?
•If you have a beard, a bushy mustache,or long sideburns, a regular respirator won’t protect you because the mustache, beard or sideburns keep it from making a tight seal on your face. You need to use a special respirator.
•If your foreman doesn’t have one of these special respirators, you cannot do the work.”Excerpted from California Department of Pesticide Regulation‘s publication PSIS A-5.

For the rest of us who may be required to apply pesticides in the course of their employment, we may feel that well fitted gas masks provide complete protection against inhalation of fumes. Well, if that is what you have come to believe, keep in mind that one of the ways employers know when to change a filter is when YOU report an unusual smell or taste. READ ON.

“HOW CAN I TELL IF MY RESPIRATOR IS WORKING?
Most respirators do not really clean the air.What they do is stop most harmful chemicals from getting into your lungs. They dothis with special filters. But these filters stop working after a while. Then the pesticide will pass through and you will breathe it in. If you notice a smell or taste, if your eyes or throat burn, or if it gets hard for you to breathe, leave the area RIGHT AWAY. Go to a safe area that contains nopesticides. Then take off your respirator and look at it carefully. Is it torn or worn out? If there are no cracks or other problems you can see, you may need to change the filter.
Because many pesticides do not have a smell or cause irritation, your employer must replace the filter often.
THE FILTER MUST BE REPLACED
•when directions on the pesticide label say so, or
•when the respirator maker says it should be replaced, or
•when you first notice smell, taste or irritation, or
•at the end of each workday.
Follow the rule that replaces the filter soonest.
REMEMBER: Respirators only protect you from breathing chemicals. Most of the time when pesticides are used, protecting your skin is also important.”

Employers are required to provide complete information about the chemicals that you may be applying and their effects on you and the environment, and they are required as well to provide working, fitted protective equipment, including gas masks for volatile chemicals. If these excerpts frighten you or make you angry, read the fine print on the bottle,  ask questions, and don’t work with a chemical until you understand the risks–find your employer’s Material Safety Data Sheets for the chemicals that you apply and READ ON!!!

Why it is important to read the herbicide label for recommended rate and ‘INACTIVE’ ingredients . . .

29 Feb

How many people read the label before going out and spraying the weeds in their back yards? Home owners are renowned for believing that if some is good, more must be better. Do they use protective gear like long sleeves? “In the summer? Are you kidding? No way!” What about the inactive ingredients? Obviously if they are inactive ingredients they must be less toxic than the active ones, right? WRONG!
A few weeks ago in my Weed Science course at UC Davis (a fabulous class, I recommend it highly), I learned that much suffering could have been averted if only Agent Orange were made more carefully, without as much Dioxin (a very hazardous contaminant that was not needed for defoliation, but was sprayed right along with the defoliants during the Vietnam War).
In a 5 part series, the Chicago Tribune Watchdog column story goes into some depth and interviews victims of this manufacturing oversight.

Check it out. Why is this not taught in history class? We have enough chemistry to understand this in high school. Please give us your 2 cents on this one!!
