Spraying Operations


This checklist is not all-inclusive. You should add to it or delete items that do not apply to your business; however, carefully consider each item and make your decision. You should refer to Minnesota statutes and rules, and federal OSHA standards adopted by reference in Minnesota for specific guidance that may apply to your work situation (see www.dli.mn.gov/). (Note: This checklist is typical for general industry but not for construction or maritime industries.)
