Safe Use of Aerosols

The applicator, the customer and the environment alike can benefit from the advantages offered by aerosol products. Using this technology, PCOs need not measure or mix insecticide concentrates. Since the contents are sealed within prepressurized containers, applicator exposure to concentrates is virtually eliminated. Because no mixing is necessary, economic concerns about waste, spillage and evaporation also are reduced.

In addition, the prepressurized container always carries the use label for easy reference by the PCOs on the job. The label directs the technician in the rate of application for maximum insect control in specific locations and for specific pests, thus enhancing the technician’s efficiency. Container disposal directions also are included on each label.

SAFETY PRECAUTIONS. As a result of the aforementioned advantages, aerosol products have grown in popularity in recent years, resulting in a need for practical, "hands-on" safety information about this important product group. What follows are some basic guidelines describing how to use aerosol products safely and effectively:

Preparation for use. Any cans which have indentations or distended bottoms should not be used. Pay careful attention to any directions to shake the container before using since shaking helps assure proper operation of the container.

Storing prepressurized insecticides. In vehicles, prepressurized containers should be stored in locked carriers away from sunlight (below 130 degrees Fahrenheit). Even though most prepressurized insecticides carry no expiration date, it is important to rotate stock to insure that the oldest products are used first. Cans should be stored at room temperature prior to use for optimum performance.

Using prepressurized insecticides. Eye protection (safety glasses) should be worn when applying prepressurized insecticides.

When making space/ULV applications, PCOs should wear a respirator. Wet sprays should not contact painted, plastic or varnished surfaces.

Using prepressurized insecticides near electric or electronic equipment. As a general rule, insecticides should not be applied to electronic equipment such as microwave ovens, computers, telephones, televisions and VCRs. Some non-water-based products can be used in such areas as switch boxes, conduits and outlet boxes. Be sure to check the label to confirm where the product can be used.

Container disposal. Follow the label directions and your state regulations which recommend methods of prepressurized insecticide container disposal. Do not incinerate or puncture any prepressurized container.

CONCLUSION. The same care and caution should be taken when handling and applying prepressurized insecticides as with other non-pressurized insecticides. The most important precautionary measure any PCO can take before applying any type of insecticide, including those packaged in prepressurized packages, is to READ AND FOLLOW LABEL DIRECTIONS.
