Acid Gases Covered by the 7582P100L
The 7582P100L uses a specialized sorbent material that targets inorganic acid gases. NIOSH-approved gases include:
- HCl (Hydrogen chloride / hydrochloric acid mist) — metal pickling, semiconductor fabrication, chemical synthesis
- HF (Hydrogen fluoride) — glass etching, semiconductor manufacturing, petroleum refining
- SO₂ (Sulfur dioxide) — combustion processes, paper pulping, chemical plants
- Cl₂ (Chlorine gas) — water treatment, chemical manufacturing, pulp bleaching
- HBr (Hydrogen bromide) — semiconductor processing, organic synthesis
- HCN (Hydrogen cyanide) — electroplating, fumigation (short-duration only)
- HCHO (Formaldehyde) — laboratory work, embalming, composite manufacturing
Important: the 7582P100L does NOT protect against organic vapors. If your chemical environment also contains organic solvents, use the 7583P100L OV+AG+P100 which provides broader coverage at similar or lower cost.
7582P100L vs. 7583P100L: Why the 7583 Usually Wins
| Attribute | 7582P100L vs. 7583P100L |
|---|---|
| Acid gas protection | Yes (both) |
| OV protection | No |
| P100 protection | Yes (both) |
| Price | Higher for less coverage |
| Best use case | Pure acid gas environments only |
In most industrial environments, organic vapors are present alongside acid gases. The 7583P100L adds OV protection at a lower price than the 7582P100L — making it the better default unless your industrial hygiene assessment has formally confirmed organic vapors are absent.
Primary Applications for the 7582P100L

Frequently Asked Questions
Q: What acid gases does the 7582P100L protect against?
A: The 7582P100L provides NIOSH-approved protection against hydrogen chloride (HCl), hydrogen fluoride (HF), sulfur dioxide (SOâ‚‚), chlorine (Clâ‚‚), hydrogen bromide (HBr), hydrogen cyanide (HCN), and formaldehyde (HCHO). It does not protect against organic vapors or ammonia.
Q: Does the 7582P100L protect against organic vapors?
A: No — the 7582P100L is an acid gas + P100 cartridge. It does not contain the activated carbon required for organic vapor adsorption. If organic vapors may be present alongside acid gases, use the 7583P100L (OV+AG+P100) instead.
Q: When should I choose 7582P100L over 7583P100L?
A: Only when your industrial hygiene assessment has formally documented that organic vapors are not present in your work environment. If there is any uncertainty, the 7583P100L provides broader coverage at lower cost and is generally the preferred choice.
Q: Is the 7582P100L approved for hydrogen cyanide?
A: Yes — the 7582P100L is NIOSH-approved for hydrogen cyanide (HCN). However, HCN has an IDLH of only 50 ppm, and concentrations above the OSHA PEL (10 ppm TWA) require careful engineering control verification before relying on a half-face APF 10 respirator.
Q: Can I use the 7582P100L for formaldehyde exposure?
A: Yes — the 7582P100L provides NIOSH-approved formaldehyde protection under OSHA 1910.1048 (Formaldehyde standard). The OSHA PEL for formaldehyde is 0.75 ppm TWA; the STEL is 2 ppm. A half-face respirator with APF 10 protects up to 7.5 ppm TWA.
Q: How long do 7582P100L cartridges last?
A: Acid gas cartridge service life depends on the specific gas concentration, temperature, humidity, and breathing rate. OSHA requires a written change schedule. Replace immediately if you detect any acid gas odor or taste — most acid gases have IDLH values low enough that taste/odor detection means you are already approaching unacceptable exposure levels.
Q: What respirators are compatible with the 7582P100L?
A: All Honeywell North bayonet-mount respirators: the 5500 Series half-face, 7600 Series full-face, and 5400 Series full-face. Not compatible with 3M, MSA, or other brands.
Q: Does the 7582P100L protect against chlorine gas?
A: Yes — Cl₂ (chlorine gas) is one of the NIOSH-approved gases for the 7582P100L. OSHA PEL for chlorine is 1 ppm ceiling. APF 10 (half-face) provides protection up to 10 ppm. For chlorine concentrations above 10 ppm, use a full-face respirator (APF 50) with 7582P100L cartridges.
Q: Is the 7582P100L NIOSH-approved?
A: Yes — NIOSH-approved under 42 CFR Part 84 for acid gas + P100 protection when used with compatible Honeywell North bayonet respirators.
Q: What is the OSHA APF with 7582P100L cartridges?
A: APF 10 with a North half-face respirator; APF 50 with a North full-face respirator. The cartridge type determines the chemical coverage; the respirator type determines the protection factor.
Q: Can I use 7582P100L for sulfur dioxide in a paper mill?
A: Yes — SO₂ is a listed gas for the 7582P100L. However, paper mill environments often also contain organic compounds — verify with an IH assessment whether 7583P100L (with OV coverage) is more appropriate for your specific process.
Q: What happens if I use 7582P100L in an environment with organic vapors?
A: Organic vapors would pass through the acid gas sorbent unimpeded — the cartridge would provide no protection against them. This is a serious health hazard. Always verify the specific chemical hazards in your environment with an industrial hygiene assessment before selecting cartridges.

A: Available at WC Safety. Browse the full Honeywell North cartridge lineup.
OSHA Assigned Protection Factors: Respirator Type Determines Protection Level
A critical and frequently misunderstood principle: the protection factor (APF) is determined by the respirator type, not the cartridge. The cartridge determines which chemicals are protected against; the facepiece type determines how much protection is provided relative to the permissible exposure limit (PEL).
| Respirator Type | OSHA APF (29 CFR 1910.134 App A) |
|---|---|
| Half-face air-purifying (e.g., North 5500 Series) | APF 10 — protects up to 10× the PEL |
| Full-face air-purifying (e.g., North 7600/5400 Series) | APF 50 — protects up to 50× the PEL |
| Powered air-purifying (PAPR), half-face | APF 50 |
| Powered air-purifying (PAPR), full-face/hood | APF 1000 |
Example: if the OSHA PEL for a solvent is 100 ppm, a half-face respirator (APF 10) with the appropriate cartridge protects up to 1,000 ppm; a full-face (APF 50) protects up to 5,000 ppm. If your measured air concentration exceeds the APF × PEL product, you need a higher APF respirator or must implement engineering controls to reduce concentration.
OSHA 1910.134 Cartridge Change Schedule Requirements
OSHA 29 CFR 1910.134(d)(3)(iii)(B) requires that atmospheres immediately dangerous to life or health (IDLH), oxygen-deficient atmospheres, and environments with gas or vapor cartridges must have a cartridge change schedule based on objective information. Specifically, the standard requires:
- A written change schedule based on objective data — measured concentrations, published service life tables, or ESLI (end-of-service-life indicator) performance data
- The change schedule must address the specific chemicals present, their concentrations, temperature, humidity, and work rate
- Immediate replacement when the wearer detects any odor, taste, or irritation through the cartridge — this indicates breakthrough and potential saturation
- Cartridges must be replaced before being stored and reused — carbon that has partially adsorbed contaminants may release them during storage and re-entry
- Written records of the change schedule must be made available to employees upon request
Failure to maintain a written cartridge change schedule is one of the most commonly cited OSHA violations in respiratory protection programs. If you are building or auditing a respiratory protection program, the OSHA Small Entity Compliance Guide for Respiratory Protection (OSHA 3384) provides a detailed walkthrough of change schedule requirements.
Regulatory Standards for Acid Gas Environments
Several OSHA and regulatory standards specifically address the acid gases covered by the 7582P100L:
- HF (Hydrogen Fluoride): OSHA PEL 3 ppm TWA; ACGIH TLV 0.5 ppm ceiling; NIOSH IDLH 30 ppm. Semiconductor and glass etching operations are primary regulated applications
- HCl (Hydrogen Chloride): OSHA PEL 5 ppm ceiling; ACGIH TLV 2 ppm ceiling; NIOSH IDLH 50 ppm. Metal pickling and chemical synthesis
- Clâ‚‚ (Chlorine): OSHA PEL 1 ppm ceiling; ACGIH TLV 0.1 ppm TWA; NIOSH IDLH 10 ppm. Water treatment and chlor-alkali operations
- SOâ‚‚ (Sulfur Dioxide): OSHA PEL 5 ppm TWA; ACGIH TLV 0.25 ppm TWA; NIOSH IDLH 100 ppm. Paper/pulp and combustion applications
- HCHO (Formaldehyde): OSHA PEL 0.75 ppm TWA; STEL 2 ppm; NIOSH IDLH 20 ppm. OSHA 1910.1048 sets stringent requirements for formaldehyde programs
For all acid gas applications, verify that your measured workplace concentrations multiplied by the appropriate APF remain within safe limits for the respirator type you select.
Additional Frequently Asked Questions
Q: Does the 7582P100L require a special written respiratory protection program for acid gas applications?
A: Yes — all atmosphere-supplying and air-purifying respirators used for protection against gases and vapors require a full written respiratory protection program per OSHA 29 CFR 1910.134. This includes exposure assessment, cartridge selection rationale, change schedule, fit testing, training, and program evaluation.
Q: Can the 7582P100L be used for swimming pool chlorination work?
A: Commercial pool chlorination uses high concentrations of chlorine gas or sodium hypochlorite. The 7582P100L provides Cl₂ protection — but verify that concentrations remain within the APF limits for your respirator type. For high-concentration chlorine work (chlorine gas leak response), SCBA or air-supplied respirators may be required.
Q: What is the difference between HCl gas and hydrochloric acid mist?
A: HCl gas is adsorbed by the acid gas sorbent in the 7582P100L; hydrochloric acid mist (fine droplets) is captured by the P100 filter. The 7582P100L addresses both forms because it combines gas-phase adsorption and particulate filtration. This is important for pickling operations where both HCl vapor and mist may be generated.
Q: Is the 7582P100L approved for cyanide compounds beyond HCN?
A: The 7582P100L is specifically approved for hydrogen cyanide (HCN) gas. Other cyanide compounds (sodium cyanide dust, potassium cyanide dust) are particles that are captured by the P100 filter. More complex cyanide chemistry (nitrile compounds, organic cyanides) may fall under the OV classification — confirm with your IH for specific compounds.
Q: How does the acid gas sorbent in the 7582P100L work?
A: Acid gas cartridges typically use impregnated activated carbon or specialized chemical adsorbents (such as alkali-impregnated carbon) that react with the acid gas to form stable salts. Unlike physisorption (used in standard OV cartridges), acid gas removal involves chemisorption — a chemical reaction that is more permanent and less reversible. This means acid gas capacity is harder to regenerate and cartridges should never be reused after breakthrough.
