Gloves must be worn when there is the potential for injury or exposure to skin contact from different hazards.
Not all gloves are equally effective in preventing skin contact, especially from chemical exposures. Chemicals eventually permeate gloves; however, they can be used safely for specific time periods. See gloves' characteristics!

They are used to prevent overexposure to an inhalation hazard or irritant.

A face mask is a product that covers the wearer’s nose and mouth. 
A barrier face covering is a product worn on the face specifically covering at least the wearer’s nose and mouth, with the primary purpose of providing a particulate filtration to reduce the amount of inhaled particulate material.
A surgical mask is a loose-fitting, disposable device that creates a physical barrier between the mouth and nose of the wearer and potential contaminants in the immediate environment. 
An N95 respirator is a respiratory protective device designed to achieve a very close facial fit and very efficient filtration of airborne particles. 
Dust masks can be worn against non-toxic nuisance dusts during activities like mowing, gardening, sweeping and dusting. These masks are not respirators and do not offer protection against hazardous dusts, gases or vapors.

Some tasks that have hazards can cause foot damages.
Consider the potential risks to the feet and choose footwear accordingly.
