e. Oil-based mists with N filters.

a. Follow all instructions and warnings on the use of these respirators and wear during all times of exposure. Failure to do so will reduce respirator effectiveness, wearer protection, and may result in sickness or death.

b. For proper use, ask your supervisor or call +1 (800) 421-0688 or +1 (310) 837-6500, ext. 512/550 or email

c. The user must first be trained by the employer in proper respirator use, in accordance with applicable safety and health standards, for the contaminant and exposure level in the assigned work area. A written Respiratory Training Program must be in place and followed by each user before first use. It must meet all requirements of all applicable standards, including OSHA 29 CFR 1910.134, and in Canada Z 94.4, e.g. training, fit testing, medical evaluation, and applicable OSHA substance specific standards.

d. The vapors, gases, dusts, mists, fumes, and other contaminants which can be dangerous to your health include those which you cannot see, taste, or smell.

e. Check with your supervisor for the appropriate cartridges and/or filters for the contaminants in your work area.

f. A qualitative or quantitative fit test for half mask respirators must be performed before a respirator is assigned. For the 9000, a qualitative fit test for up to 10X PEL, or quantitative fit test, for up to 50X PEL, must be performed before a respirator is assigned. Refer to current OSHA 29 CFR 1910.134 (f).

g. This respirator, when combined with the appropriate filter, offers nuisance level relief from organic vapors and acid gases that are below the Permissible Exposure Limit (PEL). Nuisance level refers to concentrations not exceeding the OSHA PEL or other government occupational exposure limits, whichever is lower.

a. This respirator does not supply oxygen and must not be used in atmospheres containing less than 19.5% oxygen.

b. Do not remain in contaminated area if any physical distress occurs, for example breathing difficulty, dizziness or nausea.

c. Leave contaminated area and replace respirator and/or cartridge or filter if it is damaged, distorted, a proper fit cannot be obtained, you taste, smell or become irritated by contaminants, or breathing becomes difficult.

d. Do not alter, modify, or abuse this respirator.

e. Store respirator in sealed bag in a clean, dry, non-contaminated area.

f. Dispose of facepiece, and/or cartridges and disks/filters according to your employer’s policy and local regulations.

g. N, R or P filters are required for particulates.

h. Where oil mists are present, either alone or in combination with solid particulates, do not use the R or P filters for longer than one eight-hour work shift. Dispose no later than eight hours after first use. Do not exceed 10X PEL (50x the PEL for the 9000 when it has been quantitatively fit tested.) or a total of 200 mg loading per respirator, whichever is lower. It is the user’s responsibility to know the PEL and concentration of the contaminant, the maximum work rate of the employee, and any other work site-specific information to calculate the loading of the filter. Where oil mists are present do not use N filters.

i. Where NO oil mists are present, dispose of all cartridges and N, R, and P filters no later than 30 days after first use, and/or removing from sealed package, whichever occurs first.

j. Use cartridges, filters, and facepieces before the “use by” expiration date printed on box or bag.

k. If used for welding, wear appropriate eye and face protection.

The following restrictions may apply. See NIOSH Approval Label.

A. Not for use in atmospheres containing less than 19.5% oxygen.

B. Not for use in atmospheres immediately dangerous to life or health.

C. Do not exceed maximum use concentrations established by regulatory standards.

H. Follow established cartridge change schedules to ensure that cartridges are replaced before breakthrough occurs.

J. Failure to properly use and maintain this product could result in injury or death.

L. Follow the manufacturer’s User’s Instructions for changing cartridges, and/or filters.

M. All approved respirators shall be selected, fitted, used, and maintained in accordance with MSHA, OSHA, and other applicable regulations.

N. Never substitute, modify, add, or omit parts. Use only exact replacement parts in the configuration as specified by the manufacturer.

O. Refer to User’s Instructions, and/or maintenance manuals for information on use and maintenance of these respirators.

P. NIOSH does not evaluate respirators for use as surgical masks.

S. Special or critical user’s Instructions and/or specific use limitations apply. Refer to User’s Instructions before donning.

Inspect your respirator before and after wearing. Do not wear, and return to your supervisor if:

1. Head harness is torn, cut, or damaged in any way, or if head straps are torn, cut, or have lost elasticity.

2. Buckles or head cradle are missing, damaged or broken.

3. Facepiece is cracked, torn, distorted, dirty, or has holes.

4. Inhalation/Exhalation diaphragms and/or gaskets are missing, torn, damaged, or not properly seated.

5. Cartridges are at the end of their service life, cracked, damaged, or not properly seated.

6. Any other plastic or rubber part is cracked, distorted, or damaged.

1. Review NIOSH labels on appropriate approval matrix.

A qualitative or quantitative fit test must be performed before a respirator is assigned. Refer to current OSHA and/or NIOSH regulations, current ANSI Standards, and all other applicable regulations for complete details.

Qualitative fit testing can be performed using BITREX® with appropriate cartridges or filters.
Quantitative fit testing can be performed with cartridges fitted with probes. (This will be covered in Chapters X & XI.)

1. Users must follow instructions each time respirator is worn.

2. OSHA regulations 29 CFR 1910.134 (f) requires that the user be fit tested.

3. If you cannot obtain a proper fit, do not enter the contaminated area and see your supervisor.

4. Fit testing ensures that a respirator fits each individual wearer and is not the same as a user seal check.

5. A new fit test must be conducted any time the user changes respirator models or sizes. Also see OSHA 29CFR 1910.134.

6. See appropriate Chapter (VI, VII or VIII as appropriate) and 7000/7800/8000/9000 Instruction Manual for proper fitting instructions.

7. The test subject must be clean-shaven. Do not test a subject with a beard or o  ther facial hair, which prevents contact between the face and the seal of the respirator.


Leave contaminated area, and replace cartridges, if you smell, taste, or feel any irritation, in your nose or throat. Consult your supervisor. Replace according to your changeout schedule per OSHA 1910.134, or no more than eight hours after first use, or sooner if breakthrough occurs. Dispose of all cartridges no later than thirty days after first use.


OSHA 1910.134 (d) requires that the employer implement a change out schedule for cartridges based on objective information or data that will ensure cartridges are changed before the end of their service life (see OSHA 1910.134 for complete text). A cartridge’s useful service life is how long it provides adequate protection from harmful chemicals in the air. The service life of a cartridge depends on many factors, including environmental conditions, breathing rate, cartridge filtering capacity and the amount of contaminants in the air.

If you know what the chemical is and how much of it you are exposed to, then you are ready to estimate how long your respirator cartridges will work and apply the safety factor.

You must use some type of objective data to develop a change out schedule. Options for determining a cartridge’s service life include:

1. Conducting experimental tests.
2. Using a mathematical model

OSHA has on its website other means of calculating breakthrough times for various chemicals. You may also wish to consider use of this website in developing your change out schedules. Be advised that actual service life can vary considerably from those calculated using these methods. These methods only provide rough estimates. Some of the data you will need specific to the Moldex cartridges in order to use the models on the OSHA website are:

• #7100 has an adsorbing equivalent of 42.5 grams Organic Vapor Carbon, its height is
2.18 cm, inside diameter is 7.78 cm.

• #7600 has an adsorbing equivalent of 36.0 grams Organic Vapor Carbon, it’s height is
2.18 cm, inside diameter is 7.78 cm.

• A change out schedule worksheet is provided.



These weights were estimated by Assay Technologies using methods based on their tests. It is suggested that you use default values provided by OSHA for the other cartridge specific parameters. Lastly, in order for the OSHA models to be used you may have to provide other pertinent data on the challenge agent which may be found on the SDS or from the chemical manufacturer. These methods can be found at:

They are called “Respirator Change Schedules.”Moldex suggests that you use the OSHA methods, or other means provided by OSHA. Moldex always recommends that you utilize the most conservative (shortest) breakthrough times. Moldex recommends that you use any of the methods only for the contaminants contained in the Moldex Chemical Selection Guide. For more detailed information on these methods, refer to OSHA’s website at:
