821.2 Safety
Definition: Proper handling of herbicides
Why: Proper safety must be a priority for herbicide applications as it is with all MoDOT operations. Worker and public safety are important factors in a successful herbicide program. The following can be referred to for safe handling, storage, mixing and application of herbicides.
- 1. Product Label - Provided by manufacturer
- 2. Material Safety Data Sheets - Provided by manufacturer
- 3. Safety Policies, Rules & Regulations - MoDOT
- 4. Traffic Control for Field Operations - MoDOT
MoDOT requirements for proper Personal Protection Equipment (PPE) can be found in the Safety Policies, Rules and Regulations Employee Handbook. More PPE than the label or MoDOT requires can be worn. It is best to protect yourself to the fullest extent.
Methods:
A. Handling Herbicides
The following PPEs are recommended by MoDOT when handling herbicides. The MSDS for each herbicide is the final authority on PPEs required.
- 1. Long sleeve shirt and pants (disposable chemical suit is best)
- 2. Rubber boots
- 3. Neoprene gloves designed for chemical handling
- 4. Chemical goggles or face shield
- 5. Respirator (unless not required by MSDS)
- 6. Apron – Neoprene or rubber
B. Handgun Applications
Long sleeve shirt, pants (chem suit), goggles or face shield, rubber boots and rubber gloves must be worn for all handgun applications.
C. Respirator is required when mixing/applying the following products:
Some 2,4-D formulations (Check label/MSDS before use. Check MSDS for any products used not listed above.)
D. Broadcast (spray bar or boom) Applications
- 1. PPE such as gloves, goggles and respirators may be removed if the application is made from an enclosed cab of a truck or tractor.
- 2. Keep PPE clean and accessible should you need to get out of the cab.
- 3. PPE must be worn if applicator is not in an enclosed cab. Spills are addressed in 821.14.
Special Recommendations: Read the label. The PPE listed in the product label and MSDS is the minimum requirement.
