GENERAL SAFETY INFORMATION

Intended Use

The 3M™ Portable Compressed Air Filter & Regulator Panel 256-02-00, with Carbon Monoxide

(CO) Filtration and Monitor is intended to filter and regulate compressed air to be used with

supplied air respiratory protection systems.

List of Warnings and Cautions within these User Instructions

W WARNING

The 3M™ Portable Compressed Air Filter & Regulator Panel 256-02-00, with Carbon

Monoxide (CO) Filtration and Monitor is intended to filter and regulate compressed air to be

used with supplied air respiratory protection systems. Misuse may result in sickness or death.

For proper use, see supervisor or User Instructions, or call 3M in U.S.A., 1-800-243-4630. In

Canada, call Technical Service at 1 800 267-4414.

The 3M™ Portable Compressed Air Filter and Regulator Panel 256-02-00, with CO Filtration

and Monitor should not be used when the air entering the filtering system is oxygen deficient.

These units will not increase the oxygen content of oxygen deficient air. Use with oxygen

deficient air may result in sickness or death.

The panel should not be used in an Immediately Dangerous to Life or Health atmosphere

(IDLH) unless it is used in conjunction with a back-up escape system or a Self-Contained

Breathing Apparatus/Supplied Air Respirator (SCBA/SAR), where applicable.

To meet NIOSH requirement 42 CFR 84, subpart 84.150 for minimum and maximum airflow

(4-15 cfm, 113-425 lpm), the air control valves approved for use with the 3M respirators must

be operated within the supply pressure ranges and hose lengths stated in their User Instructions.

Failure to do so may adversely affect respirator performance and result in sickness or death.

You must comply with OSHA standard 29 CFR 1910.134, which states that, "Airline couplings

shall be incompatible with outlets for other gas systems to prevent inadvertent servicing of

airline respirators with nonrespirable gases or oxygen." In Canada, refer to the requirements of

CSA standard Z180.1. Failure to do so may result in sickness or death.

Your employer must provide breathing air that meets at least the requirements of the

specification for Grade D breathing air, as described in the Compressed Gas Association

Commodity Specification G-7.1-1997 in the United States. In Canada, refer to CSA standard

Z180.1, table for the quality of compressed breathing air. Failure to do so may result in

sickness or death.

There is no assurance that by using the 3M™ Portable Compressed Air Filter and Regulator

Panel 256-02-00, with Carbon Monoxide Filtration and Monitor the filtered compressed air will

meet the requirements of Grade D breathing air. In Canada, refer to the requirements of CSA

standard Z180.1.

The line pressure must be kept within safe limits, 125 psig (8.75 kg/cm

and water, unless trapped or filtered out, may continue downstream in concentrated form and

adversely affect the performance of the respirator and may result in sickness or death.

adapter is used.

) maximum. Dirt, oil

W WARNING

Carbon monoxide monitor will alarm if carbon monoxide concentrations exceed the preset level

(10 ppm USA; 5 ppm Canada). If alarm should sound, remove respirator or activate SCBA

and immediately move to a safe, breathable atmosphere. Have the proper qualified personnel

examine the equipment and make the appropriate corrections before using again. Failure to do

so may result in sickness or death.

Use of equipment described in these User Instructions must be in accordance with applicable

health and safety standards, respirator selection tables contained in such publications as ANSI

Z88.2-1992, CSA Standard Z94.4, or pursuant to the recommendations of an industrial

hygienist. The employer must have a written respirator program in place which is in

accordance with the OSHA respiratory protection standard found in 29 CFR 1910.134 prior to

using any respirator. In Canada, follow CSA Standard Z94.4 or the requirements of the

authority having jurisdiction in your region.

Each person using this equipment must read and understand the information in these User

Instructions. Use of this equipment by untrained or unqualified persons, or use that is not in

accordance with these User Instructions, may adversely affect product performance and result

in sickness or death.

Do not use for respiratory protection when atmospheric concentrations of contaminants are

unknown or immediately dangerous to life or health, unless used in conjunction with a back-up

escape system or a self-contained breathing apparatus/supplied air respirator (SCBA/SAR).

Leave work areas immediately if:

– Any part of the system becomes damaged.

– Air flow into the respirator is reduced or stops.

– Breathing becomes difficult.

– Dizziness or other distress occurs; or

– You taste or smell contaminants or an irritation occurs.

Never alter or modify this assembly.

Not for use in any way other than in accordance with the use and maintenance instructions in

this manual.

Do not use if any parts are missing or damaged.

Air supply piping, fittings, and compressors must have the capacity to deliver sufficient air

volume to operate each air regulating valve at the recommended pressure.

Serious injury could result if the AIR SAMPLE METERING VALVE is not properly adjusted.

Proper sample airflow to CO monitor is required for monitor to give correct CO level readout.

Failure to do so may result in sickness or death.

Always turn off air supply and bleed air pressure before disassembling the 3M filter and

regulator panel with CO filtration or serious injury could result.

IMPORTANT

Before use, each person using this equipment must read and understand these User Instructions.

Keep these User Instructions for reference.

Do Not Use For

Filtering and regulation of air sources when airborne contaminant concentrations are unknown or

immediately dangerous to life or health (IDLH), unless used in conjunction with a back-up escape

system or a self-contained breathing apparatus/supplied air respirator (SCBA/SAR),

where applicable.
