User Training And Instructions; Why Use Respiratory Protection - Sundstrom SR 900 APR Manual Del Usuario

Chemical Cartridges
A chemical cartridge absorbs and adsorbs specific vapors and gases from a contaminated atmosphere.
This process continues until the sorbent becomes saturated and allows the contaminant to 'break-
through' the cartridge and to be detected by the user. Each chemical cartridge is designed to provide
protection only from specific contaminants. Replace chemical cartridges immediately when you detect
any contaminants inside the respirator.
Particulate filters
These filters provide protection against particulates. Sundström particulate filters trap and hold particles
in the filtering media. As the amount of the captured contaminant in the media increases, breathing
resistance also increases. Replace the filter when the change in breathing resistance becomes notice-
able. The P100 filter is 99.97% efficient against all particulate aerosols.
Combination Protective Elements
An appropriate chemical cartridge and a P100 filter can be combined to provide protection from a combina-
tion of certain vapors, gases and particulates. Replace the cartridge when you smell, taste or feel the
contaminant. Replace the filter when you begin to encounter increased breathing resistance.
Pre-filter
The Sundström pre-filter is not an independent protective element. It is designed to prevent nuisance
particulates from reaching the protective elements. This increases the life span of the primary protec-
tive element.
The pre-filter can never be used as primary protection or as a
V. USER TRAINING AND INSTRUCTIONS
This training section is designed for the user and their safety manager. It contains the minimum informa-
tion required to safely instruct users on how to don, doff, test, and change protective elements for the
Sundström respirator. This training procedure is included as a supplement to the instructions contained
in the remainder of this manual.
Local conditions may require additional instructions. Sundström encourages the safety professional
responsible for the respiratory program to add all local information possible to increase worker safety and
to supplement this basic text. You can obtain an Instructors Guide from your nearest Sundström Distributor.
