Understanding Safety Hazards in Chemical Safety

Chemical safety hazards are the conditions, substances, or work practices that can cause injury, illness, property damage, or environmental harm when hazardous chemicals are used, stored, transported, or disposed of. In many workplaces, the biggest risks aren’t dramatic spills—they’re routine tasks performed without clear hazard communication, consistent labeling, and fast access to the right Safety Data Sheet (SDS).

OSHA’s Hazard Communication Standard (HCS), 29 CFR 1910.1200, requires employers to identify chemical hazards, ensure proper labels, maintain SDS access, and train employees. When these elements are fragmented across binders, shared drives, and outdated inventories, safety hazards multiply.

Key takeaway: Most chemical incidents are preventable when hazard information is accurate, accessible, and understood at the point of use.

Workplace Hazard Categories: Where Chemical Risks Fit

“Workplace hazard categories” is a practical way to group risks so teams can recognize them quickly and control them consistently. Chemical safety hazards often overlap with other categories (for example, flammables introduce fire/explosion risks).

Common workplace hazard categories

  • Chemical hazards: Toxicity, corrosivity, sensitizers, carcinogens, reactive chemicals, asphyxiants
  • Physical hazards: Slips/trips/falls, noise, heat/cold stress, moving equipment
  • Biological hazards: Bloodborne pathogens, mold, bacteria
  • Ergonomic hazards: Repetitive motion, awkward postures, manual handling
  • Safety/operational hazards: Confined spaces, electrical, lockout/tagout, hot work

In chemical safety programs, the goal is to translate “chemical hazards” into actionable controls: correct PPE, compatible storage, ventilation needs, spill response steps, and emergency measures.

Core Chemical Safety Hazards (and Why They Matter)

Health hazards (acute and chronic)

Health hazards involve direct harm to the body. Under OSHA HCS and the Globally Harmonized System (GHS), many health effects are communicated through hazard classes (e.g., acute toxicity, skin corrosion, respiratory sensitization, carcinogenicity).

Examples include:

  • Corrosives causing skin and eye burns (e.g., strong acids/bases)
  • Toxins causing poisoning through inhalation, ingestion, or skin absorption
  • Sensitizers triggering asthma or allergic skin reactions
  • Carcinogens and reproductive toxins creating long-term risk from repeated exposure

Controls should be based on exposure routes:

  • Engineering controls (local exhaust ventilation, closed transfer systems)
  • Administrative controls (standard operating procedures, restricted access)
  • PPE (chemical-resistant gloves, goggles/face shields, respirators when required)

Physical hazards (fire, explosion, reactivity)

Many chemicals present physical hazards that can injure workers and damage facilities quickly.

  • Flammables: Vapors can ignite from static discharge or nearby ignition sources
  • Oxidizers: Intensify fires, react violently with incompatible materials
  • Compressed gases: Projectile risk, asphyxiation risk, cylinder handling hazards
  • Water-reactive or self-reactive chemicals: Heat release, toxic gas formation

Under OSHA HCS, these hazards must be classified and communicated on labels and SDSs. Practically, that means workers need fast answers to questions like: “Can this be stored next to that?” and “What extinguisher is appropriate?”

Exposure hazards during routine tasks

Chemical exposure doesn’t only occur during manufacturing. It occurs during cleaning, maintenance, sampling, decanting, and waste handling. Common exposure-related safety hazards include:

  • Decanting into secondary containers without labeling
  • Aerosolization from spraying cleaners or solvents
  • Poor ventilation in mixing rooms or enclosed spaces
  • Skin contact from inadequate glove selection or breakthrough

OSHA requires that SDSs be readily accessible during each work shift (29 CFR 1910.1200(g)(8)). If employees can’t quickly locate the current SDS, they may improvise controls—or skip them.

Hazard Communication: The Backbone of Chemical Safety

OSHA’s HazCom standard (29 CFR 1910.1200) is central to preventing chemical safety hazards. It focuses on ensuring that chemical hazard information is effectively communicated to employees.

What OSHA expects under 29 CFR 1910.1200

Employers generally must:

  1. Maintain a written hazard communication program
  2. Keep a chemical inventory list
  3. Ensure container labeling (including secondary containers as applicable)
  4. Maintain Safety Data Sheets for hazardous chemicals
  5. Provide effective employee training at initial assignment and when new hazards are introduced

Why SDS management breaks down

SDS systems fail when:

  • SDS binders are incomplete or outdated
  • Multiple locations use different versions of the same SDS
  • Chemical inventories don’t match what’s actually on site
  • Workers can’t access SDSs in the field (maintenance, remote areas, after hours)

This is where a centralized system makes a measurable difference. SwiftSDS helps organizations reduce these safety hazards by providing a centralized SDS library, chemical inventory management, and mobile access so workers can pull up the right SDS instantly—without hunting for binders or relying on memory.

Using SDS Information to Control Safety Hazards

An SDS is more than a compliance document; it’s a hazard-control tool. Training employees to use the SDS helps transform chemical safety from “rules to follow” into “risks to manage.”

SDS sections that directly address safety hazards

  • Section 2 (Hazard Identification): GHS classification, pictograms, signal word, hazard statements
  • Section 4 (First-Aid Measures): Immediate response actions by exposure route
  • Section 7 (Handling and Storage): Incompatibilities, safe storage conditions
  • Section 8 (Exposure Controls/PPE): Limits, engineering controls, PPE recommendations
  • Section 10 (Stability and Reactivity): Conditions to avoid, incompatible materials, hazardous decomposition
  • Section 6 (Accidental Release Measures): Spill response and containment

If employees routinely check Sections 2, 7, 8, and 10 before using a chemical, many high-risk errors (wrong gloves, incompatible storage, poor ventilation) are avoided.

Practical Controls That Reduce Chemical Safety Hazards

A strong chemical safety program aligns hazard communication with day-to-day controls.

High-impact practices to implement

  • Standardize labeling for all secondary containers and process vessels
  • Segregate storage by compatibility (flammables, acids, bases, oxidizers, toxics)
  • Inspect chemical containers for leaks, corrosion, and missing labels
  • Use exposure-based PPE selection (not “one glove fits all”)
  • Plan spill response with appropriate absorbents and neutralizers
  • Track expiration dates where stability degrades or peroxides may form
  • Ensure emergency equipment readiness (eyewash/showers) where corrosives are used

SwiftSDS supports these controls by linking SDS access to a live chemical inventory—including locations, quantities, and expiration dates—so supervisors can identify hotspots (e.g., too much flammable storage in one area) and correct issues before they become incidents.

Strengthening Training and Readiness

OSHA requires HazCom training that enables employees to recognize hazards and understand protective measures. Effective training is practical and task-based:

  • Teach how to read container labels and match them to SDS information
  • Review job-specific scenarios (mixing, transferring, cleaning, maintenance)
  • Reinforce when to escalate (unusual odors, symptoms, spills, incompatible storage)
  • Practice quick SDS retrieval during drills

Mobile SDS access is especially valuable for maintenance, facilities, and field teams. With SwiftSDS, workers can retrieve SDS information from any device, supporting faster decisions during routine work and emergencies.

Conclusion: Reduce Safety Hazards with Better Hazard Visibility

Chemical safety hazards are manageable when workplaces clearly identify hazards, communicate them effectively, and apply controls consistently. By organizing risks within workplace hazard categories, teams can spot overlaps (chemical + fire + confined space) and plan controls that actually match the task.

If SDS access, inventory tracking, and version control are pain points, a purpose-built platform can close critical gaps.
