Introduction

Inorganic chemicals and gases such as ammonia, chlorine, sulfur dioxide, nitrogen oxides, ozone, and hydrogen sulfide are widely used or generated in industrial manufacturing, wastewater treatment, pulp and paper processing, fertilizers, semiconductor production, and combustion systems. These gases can cause acute toxicity, corrosion, respiratory irritation, and life-threatening exposures even at low concentrations.

AGT Labs provides accredited monitoring, sampling media, and laboratory analysis to evaluate airborne concentrations, verify engineering controls, and maintain compliance with OSHA PELs, ACGIH TLVs, and emergency response requirements.

Industrial Sources of Inorganic Chemicals & Reactive Gas Release

Reactive inorganic gases are commonly released during operations such as:

Ammonia compression, refrigeration, and fertilizer systems
Chlorine gas handling, storage, and disinfection processes
SO₂ and NOx generation from boilers and combustion units
H₂S release from wastewater treatment and petroleum refining
Chemical reactions producing acid gases or corrosive by-products
Leaks from pipelines, flanges, valves, and gas cylinders

Understanding these sources helps select correct sampling media and design appropriate monitoring strategies.

Purpose

Industrial operations involving ammonia, chlorine, sulfur dioxide, nitrogen oxides, and hydrogen sulfide require reliable air monitoring to prevent acute toxicity and corrosion damage. AGT Labs quantifies toxic and corrosive inorganic chemicals and gases to verify compliance with OSHA and ACGIH exposure limits and ensure emergency preparedness.

Testing Overview

Sampling follows NIOSH methods: 6013 (H₂S), 6014 (SO₂), 6016 (NO₂), 6017 (NH₃), and 6019 (Cl₂).

Gases captured on chemically treated sorbent tubes or impingers
Analyzed by Ion Chromatography (IC) or UV-Vis spectrophotometry
Direct-reading instruments may be used for leak detection

Testing Options

Personal Breathing-Zone Monitoring

Assess worker exposure to toxic gases via integrated or real-time methods.

Area & Confined-Space Sampling

Monitoring for maintenance, shutdowns, and high-risk operations.

Short-Term & TWA Measurements

STEL and time-weighted average exposure assessment.

Ambient & Community Assessment

Evaluate off-site impacts near industrial areas.

Emergency Incident Response

Rapid post-release verification and corrective actions.

Sampling Media & Equipment Supply

Chemically treated sorbent tubes specific to target gases
Glass impingers with absorption solutions
Low-flow sampling pumps (100–500 mL/min)
Calibration gases and chain-of-custody documentation

All supplies are delivered pre-conditioned with stability certificates.

Sampling Guidelines

Use media matched to gas chemistry
Protect samples from heat and light
Calibrate instruments using certified gases
Document process conditions and duration

Strategies for Monitoring Toxic & Corrosive Gas Exposures

Reliable monitoring includes a combination of integrated sampling, real-time sensors, and task-based assessments. High-risk scenarios include confined space entry, chemical charging, startup/shutdown cycles, and emergency releases.

Direct-reading instruments for leaks and spikes
Integrated sampling for regulatory compliance
Continuous fixed monitoring for critical processes
Validation of scrubbers, ventilation systems, and alarms

These strategies in inorganic chemicals ensure comprehensive exposure evaluation and support rapid response during abnormal conditions.

Accreditation & Standards

NIOSH 6013–6019 OSHA ID-101 / ID-103 ISO/IEC 17025 AIHA-LAP Industrial Hygiene
