The unit is a molded mask that covers the user’s nose and mouth, held in place by two elastic straps. Main uses for the disposable particulate respirator include protection from dusts, mists, and some fumes in jobs such as haying, applying fertilizer, and grinding feed. The disposable particulate respirator is commonly referred to as a dust mask, but it should not be confused with a nuisance dust mask. The following descriptions will help you determine the type of air-purifying respirator needed for your work. Producers who have any type of respiratory limitation, such as asthma or cardiovascular problems, should check with their physicians prior to using air-purifying respirators. This type of respirator is also called a “negative-pressure respirator” because the wearer uses his or her own breath to move air through the respirator, inhaling and pulling air through the filter. Air-Purifying RespiratorsĪir-purifying respirators are useful when working around moldy hay in areas such as barn lofts and during pesticide applications. RespiratorsĪ respirator is a device that protects the respiratory tract. There are two types of respirators: air-purifying respirators and supplied-air respirators. A nuisance dust mask is not a respirator. This type of mask provides protection against large dust particles, but provides little to no protection against smaller airborne particles. Wear this type of mask only if you have had no prior respiratory impairment and are completing a short-term task involving nontoxic dust, such as sweeping the floor of a garage or shop. A single thin elastic circles your head to secure the mask. Agricultural Safety and Health)Ī nuisance dust mask is constructed of extremely light filter paper. A single type of respiratory protection does not fit all work situations, so it is critical to identify the appropriate type of respiratory protective equipment for each situation. Your respiratory protective equipment must be properly fitted for you, designed for the job that you need to complete, and specific to your work environment. Oxygen-deficient atmosphere: Oxygen levels can be almost as low as 5% in such areas as sealed silos, manure storage facilities, and controlled atmospheric storage for fruits and vegetables.

Vapors are released from liquid applications, such as pesticides and adhesives. Gases and vapors: Gases are chemicals that are gaseous at room temperature, such as those found in silos and manure pits.Particulate contaminants: Dusts, mists, and fumes contaminate the air with particles that can be inhaled.Respiratory hazards fall into one of three categories: toxic gases in confined animal housing.(Click HERE to learn more about respiratory illnesses related to production agriculture.) Individuals who should use respiratory protection are those working around: Agricultural producers working in such conditions should wear personal protective equipment (PPE) to decrease their risk of contracting a respiratory impairment. įarmers and ranchers often work in areas where air quality can be less than ideal.
