Which piece of safety equipment is usually not needed when using pesticides with the signal word, CAUTION?

When using pesticides labeled with the signal word "CAUTION," the general perception is that these products pose a lower risk compared to those labeled with "WARNING" or "DANGER." As a result, the use of certain types of safety equipment may not be strictly necessary.

In this context, a respirator is typically the piece of safety equipment that might not be required. This is because "CAUTION" indicates that the material is less likely to cause acute harm through inhalation under standard application scenarios, assuming proper handling and application methods are followed. Consequently, individuals would usually be advised to assess the potential for inhalation exposure based on the product’s specific label instructions, but a respirator is not a common requirement.

In contrast, gloves, protective eyewear, and coveralls are generally recommended or required when handling any pesticide to protect against skin contact and eye exposure, as well as to minimize any potential risk associated with the handling of these chemicals. These pieces of equipment promote safety regardless of the signal word when dealing with pesticides.
