10 Types of Chemicals and How to Manage Them Safely

Types of chemicals and how to manage them is a critical topic for anyone working in manufacturing, healthcare, construction, laboratories, or even office environments.

Every year, workers are injured or fall ill due to improper chemical handling, poor storage, or lack of training.

Understanding the different categories of chemicals and how to manage them is key to ensuring workplace safety, compliance with regulations, and protection of both people and the environment.

1. Flammable Chemicals

Flammable substances, like gasoline, ethanol, and acetone, can ignite easily and cause explosions. These are commonly found in laboratories, garages, and manufacturing settings.

Management Tips:

• Store in approved flammable storage cabinets.
• Keep away from heat sources and open flames.
• Use non-sparking tools and proper grounding for containers.
• Implement fire suppression systems nearby.

OSHA flammable liquids guide offers standards for handling such materials.

2. Corrosive Chemicals

Corrosives like sulfuric acid, hydrochloric acid, and sodium hydroxide can destroy living tissue and metal surfaces upon contact.

Management Tips:

• Use corrosion-resistant containers and spill trays.
• Always wear chemical-resistant gloves, goggles, and aprons.
• Ensure proper ventilation and have emergency eyewash/shower stations available.
• Label containers with hazard symbols clearly.

---

3. Toxic Chemicals

These substances, such as cyanide, formaldehyde, and carbon monoxide, can be harmful or lethal even in small doses through inhalation, ingestion, or skin absorption.

Management Tips:

• Use enclosed systems or fume hoods for toxic vapors.
• Ensure proper labeling and SDS (Safety Data Sheets) are accessible.
• Train workers on first aid for exposure and proper PPE usage.
• Implement monitoring systems for airborne toxins.

Refer to Canadian Centre for Occupational Health and Safety for detailed toxic substance guidance.

4. Reactive Chemicals

Reactive chemicals like sodium, potassium, and peroxides can explode or ignite when exposed to air, water, or other chemicals.

Management Tips:

• Store in isolation from incompatible substances.
• Use sealed containers and limit quantities stored on-site.
• Train employees on what to do during violent reactions.
• Post clear hazard signs around reactive storage areas.

---

5. Compressed Gases

Compressed gases, such as oxygen, nitrogen, and acetylene, are stored under high pressure and can be hazardous if handled improperly.

Management Tips:

• Secure cylinders upright and use proper regulators.
• Store in cool, ventilated areas away from ignition sources.
• Never mix incompatible gases (e.g., oxygen with flammable gases).
• Regularly inspect hoses and fittings for leaks.

See supplier guidelines like those from ALPHAGAZ™1 With SMARTOP™ for specific gas handling protocols.

6. Oxidizers

Oxidizing agents like hydrogen peroxide and nitrates can intensify fires and cause other materials to combust more easily.

Management Tips:

• Store separately from flammable or organic materials.
• Use containers made of compatible materials (no metal lids).
• Post oxidizer warning labels clearly.
• Limit exposure to heat or sunlight.

7. Pesticides and Herbicides

Widely used in agriculture and landscaping, these chemicals can be harmful to humans, animals, and the environment.

Management Tips:

• Use only as directed and in recommended concentrations.
• Wear protective clothing and respiratory protection.
• Store in original containers with legible labels.
• Keep out of reach from non-authorized personnel and animals.

8. Solvents

Solvents like turpentine, methanol, and toluene are common in paint, cleaning, and lab work. They are often flammable and toxic.

Management Tips:

• Provide good ventilation and fume hoods where solvents are used.
• Wear gloves and safety glasses.
• Clean spills immediately with appropriate absorbents.
• Dispose of rags soaked in solvents in approved containers.

---

9. Cleaning Agents

Many cleaning products used in office and healthcare settings contain bleach, ammonia, or acids that can be dangerous when mixed or improperly handled.

Management Tips:

• Never mix bleach with ammonia—creates toxic chloramine gas.
• Label secondary containers and maintain up-to-date SDS.
• Use gloves and ventilation when cleaning enclosed spaces.
• Store separately from food preparation areas.

---

10. Biological Chemicals

These include blood, body fluids, bacteria cultures, and other infectious materials commonly handled in healthcare and lab settings.

Management Tips:

• Follow biosafety level (BSL) protocols based on risk level.
• Use biological safety cabinets for specimen handling.
• Dispose of waste in autoclave-safe biohazard bags.
• Vaccinate staff as necessary (e.g., Hepatitis B for healthcare workers).

Refer to OHSE.ca for in-depth workplace biosafety resources.
