The Compact Air PAPR uses a blower unit to force ambient air through filters/cartridges that remove contaminants, providing clean air to the user. To form a complete approved powered air-purifying respirator, the Primair Head Coverings can only be used with North Safety Products Compact Air PAPR and the appropriate filters/cartridges listed on the NIOSH Approval Labels. Part No. PA101S,M,L Description The Primair Head Cover Assembly for use with the North Compact Air PAPR. Includes Head Cover (Loose Fitting Facepiece) in small, medium or large, and Headgear PA111 The Primair Plus Head Cover Assembly, (P/N PA111 Tyvek QC or PA121 Saranex coated) for use with the North Compact Air PAPR. Includes a headcover (Tyvek QC®1 hood with bib) and headgear. PA121 The Primair Plus Head Cover Assembly for use with the North Compact Air PAPR. Includes a head cover (Saranex®2 coated Tyvek hood with bib) and headgear In addition to either the Primair or the Primair Plus, the following must be used to form a complete NIOSH approved respirator: North Safety Products Compact Air PAPR Assembly, (P/N CA101) Appropriate North Safety Products filters/cartridges 1.1 IMPORTANT INFORMATION Before using the Primair or Primair Plus Head Covering Assembly, all persons who may use or maintain this respirator must read and understand this Operating and Maintenance Instruction Manual and the Operating and Maintenance Instruction Manual provided with the approved Compact Air Blower and Battery. To use this respirator you must know that you do not have any physical limitations or illness that would preclude you from wearing this respirator (ask your Safety Director or physician). This respirator should be used or maintained only by persons who are familiar with the instructions contained within this manual. 1.1.1 TERMINOLOGY NOTE Procedures and techniques that are considered important enough to emphasize. CAUTION Procedures and techniques which, if not carefully followed, will result in damage to the equipment.

Failure to properly select the appropriate respirator for all the contaminants and their concentrations against which protection is required, or a failure to follow North’s instructions and warnings, may expose the user to the hazardous materials and the risk of serious injury, illness or death. 2. Do not use this respirator for protection against air contaminants other than those listed on the air-purifying elements and on the NIOSH Approval Label, which is supplied with the air-purifying elements. 3. Do not use this respirator under any of the following conditions: • While performing or observing abrasive blasting (sandblasting) operations. • For fire fighting. • In oxygen-deficient atmospheres (any atmosphere having less than 19.5 % oxygen by volume at sea level). • In atmospheres where the concentrations of toxic contaminants are unknown, or are Immediately Dangerous to Life or Health (IDLH). An IDLH atmosphere is any atmosphere, which has a concentration of any toxic, corrosive or asphyxiant substance that poses an immediate threat to life, which would cause irreversible debilitating effects on health, or which would interfere with the ability to escape from a dangerous atmosphere. • In atmospheres where the concentration of the contaminant exceeds the respirator’s maximum use concentrations established by applicable OSHA or other government regulations. • In poorly ventilated areas, or confined spaces such as tanks, small rooms, tunnels or vessels, unless the confined space is well ventilated and the concentration of toxic contaminants is known to be, and will continue to be, below the maximum use concentration recommended for the respirator. • In explosive atmospheres. 4. Immediately leave the contaminated area if: • Breathing becomes difficult; • Dizziness or other distress occurs; • You sense irritation, smell or taste contaminants in the work area; • The respirator becomes damaged, or if; • Airflow into the head cover or facepiece decreases significantly or stops. 5. Do not use this respiratory with the blower unit switched off. If the blower is switched off, a rapid build up of carbon dioxide ...
