At the end of this module, you will be able to:
- Define "pesticide," "pest," "acute toxicity," "chronic toxicity," "LD50," "early-entry worker," and "restricted entry interval"
- Describe major pesticide classes - herbicides, insecticides, molluscicides, fungicides, and rodenticides
- Identify the major benefits of pesticides
- Describe the roles of the EPA, WHO, and foreign governments in regulating pesticides and protecting workers
- Identify pesticide exposure hazards for humans
- List the information that is required on pesticide labels
- List storage and handling best practices for pesticides
- Identify who to contact if you have questions about pesticides or pesticide poisoning
The following key questions are answered in this module:
What is the HazCom (Hazard Communication) standard?
In the U.S., OSHA's HazCom Standard requires information on the identities and hazards of workplace chemicals to be available and understandable to workers.
How does the EPA regulate pesticides in the U.S.?
The EPA designates how they can be used, how often they can be used, and the protective equipment required. It also administers the Worker Protection Standard to protect workers.
How can pesticides help preserve wildlife habitat?
Improved farmland and cropland yields due to improved weed control and reduced damage by fungi, insects, and rodents protects wildlife habitat from being turned into farmland and cropland.
How can pesticides help protect buildings?
They can be used to protect buildings from damage caused by termites, carpenter ants, and fungi.
What is the difference between "acute" and "chronic" effects?
"Acute" effects occur after only a short exposure, while "chronic" effects take time or repeated exposures to develop.
Below is a transcript of the video sample provided for this module:
Pesticides, poisons, and other hazardous chemicals must be properly stored and handled. Storage requirements are included on pesticide labels and also in SDSs, and best practices include the following:
• Store pesticides, poisons, and related materials out of the reach of unauthorized personnel, children, and pets. A dedicated storage cabinet, room, or building that can be locked or otherwise secured is preferred, and sealed concrete floors, concrete block walls, and metal cabinets or shelves are preferred over wooden structures.
• Maintain an accurate inventory and update it whenever pesticides are added or removed.
• Group pesticides by their type or class, and label storage areas to improve access and make it easier to take inventory.
• Storage facilities should be reasonably fireproof and well ventilated.
• Do not store pesticides where flooding or water damage might occur.
