Cleaning solvents are chemical solutions commonly used for removing dirt, grease, and other contaminants from surfaces. Though convenient and effective when used properly, solvents can also pose health and safety hazards if handled improperly. Being aware of safe practices is critical for anyone working with these chemicals regularly.

This article provides 15 essential tips for safely handling and using common cleaning solvents, such as acetone, mineral spirits, naphtha, and more. Following these solvent safety guidelines will help you avoid accidents and reduce your exposure to hazardous fumes or spills. With the right precautions, cleaning solvents can be an effective tool for degreasing and cleaning without putting yourself or others at risk.

1. Use Solvents in Well-Ventilated Areas

Proper ventilation is one of the most critical precautions when using solvents. Most give off strong fumes that can irritate the eyes, nose, and throat. Breathing high concentrations of solvent vapors over time can also lead to dizziness, headaches, nausea, and long-term health issues.

Always use solvents in an area with good airflow. Work outside or near doors or windows that can be opened to allow fresh air circulation. Position fans to blow vapors away from your face. Open garage doors when degreasing auto parts or working with solvents in an enclosed space. Consider wearing a respirator mask designed to filter organic vapors if ventilation is poor.

2. Limit Skin Contact with Solvents

Direct skin exposure to cleaning solvents can lead to irritation, dryness, cracking, and increased absorption into the body. Absorption through the skin allows solvents to enter the bloodstream and circulate to internal organs.

When possible, avoid direct contact with solvents. Wear gloves designed for chemical resistance, such as nitrile, vinyl, or rubber. Long sleeves and pants also limit skin exposure. Be sure to wash your hands thoroughly after using solvents, even when wearing gloves. Moisturizing after washing helps replace skin oils that solvents remove.

3. Wear Eye Protection

Solvent splashes to the eyes must be avoided, as they can cause severe irritation or damage. Always wear protective eyewear like goggles or shielded safety glasses when handling solvents. Make sure they fit snugly to prevent vapors from reaching the eyes.

If solvent spills into the eyes, immediately flush with water for at least 15 minutes to dilute the chemical. Get medical help if irritation persists. Proper eye protection greatly reduces the risks of eye injury and vision problems from solvent exposure.

4. Use Solvents in Well-Ventilated Areas

Proper ventilation is one of the most critical precautions when using solvents. Most give off strong fumes that can irritate the eyes, nose, and throat. Breathing high concentrations of solvent vapors over time can also lead to dizziness, headaches, nausea, and long-term health issues.

Always use solvents in an area with good airflow. Work outside or near doors or windows that can be opened to allow fresh air circulation. Position fans to blow vapors away from your face. Open garage doors when degreasing auto parts or working with solvents in an enclosed space. Consider wearing a respirator mask designed to filter organic vapors if ventilation is poor.

5. Check Product Labels and Safety Data Sheets

Always read product warning labels, instructions, and safety data sheets before using a cleaning solvent. Labels provide vital information on proper use, potential hazards, recommended personal protective equipment, and emergency first aid. Safety data sheets give more extensive details about a solvent's toxicity, health effects, storage, handling, and spill protocols.

Make a note of any specific precautions needed for the solvent, such as using explosion-proof electrical equipment if it's flammable. Check that you have all recommended PPE on hand. Understanding the hazards and manufacturer guidelines will help you use the product in the safest possible manner.

6. Store Solvents Properly in Cool, Dry Places

How and where you store solvents greatly impacts fire and health risks. Keep all containers tightly sealed when not in use to avoid leaks, spills, and evaporation. Store in a cool, dry place away from direct sunlight, which can break down chemicals over time.

Never store solvents near open flames, heat sources, or incompatible materials. Solvents must also be kept away from strong oxidizers, acids, and reactive metals that could ignite a fire. Proper storage also keeps solvents safely away from children and pets. Always place large or heavy containers close to ground level for stability.

7. Use Non-Sparking Tools

Sparks can ignite flammable solvent vapors and cause containers to explode. Never use power tools, electrical equipment, or metal tools that could create sparks until vapors have fully dissipated. Make sure nearby electrical devices are suitable for hazardous locations.

Instead, use non-sparking tools made from brass, aluminum, wood or plastic when working with flammable solvents. Take added precautions when solvents are opened or poured, which can release flammable vapors. Ensure the area is well-ventilated before proceeding. Eliminating ignition sources is key to preventing solvent-related fires and injuries.

8. Control Static Electricity Buildup

Static electricity can spark and ignite solvent vapors, especially during solvent transfer between containers. Static charge builds up easily on plastic containers and synthetic clothing. Prevent static buildup by bonding and grounding when moving solvents.

Use conductive wrist straps, foot straps, and floor mats designed for static control. Ensure containers are electrically bonded before transferring solvents between them. Grounding helps dissipate static charges safely before sparking can occur. Proper bonding and grounding protect against static-related solvent ignition.

9. Use the Right Personal Protective Equipment

Choosing the right personal protective equipment (PPE) is essential for safe solvent use. Match PPE to the solvent's hazards as indicated on its safety data sheet. At a minimum, wear chemical-resistant gloves and eye protection. For toxic solvent vapors, use an organic vapor respirator.

Flame-resistant clothing, aprons, and sleeves help prevent burns if a solvent ignites. Steel-toed boots protect feet from spills. Antistatic clothing prevents static sparks. Swapping solvent-contaminated PPE for clean gear regularly limits exposure. Using recommended PPE specific to the solvent reduces risks dramatically.

10. Maintain Adequate Lighting

Proper lighting in the work area helps prevent accidental solvent spills and exposure. Bright, glare-free lighting ensures you have full visibility when handling solvent containers. Use explosion-proof lights as needed near flammable vapors.

Good visibility also lets you quickly detect leaks or other hazards. Position portable work lights to fully illuminate the area without shadows. Replace bulbs as needed to maintain bright illumination. Adequate lighting promotes safe solvent transfer and application work.

11. Control Spills Properly

Spilled solvents can create inhalation hazards, skin exposure, and fire risks if not controlled appropriately. Have absorbent cloths, sand, spill kits, or other absorbing materials on hand. For large spills, contain the area and block spills from entering drains.

Follow the product SDS for spill cleanup instructions. Apply absorbing materials to the spill, then collect and dispose of them properly. Ventilate the area to disperse vapors. Certain spilled solvents may require reporting or special clean-up methods. Control spills quickly to limit health and safety impacts.

12. Do Not Use Near Open Flames or Heat

Open flames, sparks, and heat sources easily ignite solvent vapors. Never use solvents near operating machinery, lit cigarettes, stoves, welding, or anything generating heat or sparks. Ensure good ventilation when solvent is applied in confined spaces to prevent vapor accumulation.

Preventing ignition sources is vital when working indoors or in enclosed areas where vapors cannot dissipate quickly. Use caution when working around hot equipment or bake ovens to avoid accidents. Keeping solvents away from all sources of ignition significantly reduces fire risks.

13. Use Proper Dispensing Equipment

Pouring solvents from container lids or makeshift funnels can lead to spills and exposure. Use proper dispensing equipment designed for the specific solvent. Funnels, pumps, and taps allow controlled dispensing from larger containers into smaller applicators.

Select equipment made from compatible materials that will not react with the solvent. Bond and ground dispensing equipment to control static charges during solvent transfer. Proper equipment provides better control when measuring and pouring solvents for tasks. This avoids accidental spills that waste products and creates hazards.

14. Follow Precise Mixing Instructions

Mixing certain solvents or other chemicals can be very hazardous. Follow manufacturer instructions precisely when mixing solvents. Never mix chlorinated solvents with flammable solvents - this can create toxic fumes or explosions.

Check product labels and SDS sheets for incompatible materials that should never mix with the solvent. Only mix solvents in areas with good ventilation to avoid breathing toxic fumes. Use proper bonding and grounding when transferring between containers to prevent static ignition. Precise mixing helps avoid chemical reactions that put your safety at risk.

15. Dispose of Solvents Properly

Allowing solvents to evaporate in open air or dumping down drains damages the environment. Always dispose of waste solvents appropriately. Read product SDS for proper handling as hazardous waste. Some jurisdictions require permitting for solvent hazardous waste disposal.

Typically, used solvents should be saved in sealed containers labeled as hazardous waste. Arrange pickup by a licensed disposal company that will incinerate or chemically neutralize the waste solvent. Proper disposal prevents pollution and protects the local community and ecosystem.

16. Keep Solvents Away From Skin and Eyes

Solvent splashes cause immediate skin and eye irritation and increase vapor inhalation. Avoid leaning directly over opened containers, which puts your face close to higher vapor concentrations. Hold containers below eye level when transferring solvents to reduce exposure and splash risks.

When possible, use pump-style dispensers instead of pouring from containers. Wear appropriate PPE, such as aprons, gloves, and goggles, for added protection. Keeping solvents away from mucous membranes limits potential irritation and absorption.

17. Wash Hands After Using Solvents

Even minor solvent exposure can damage skin, absorb into the body, or contaminate food and drinks. Always wash hands with soap and water immediately after using solvents. Handwashing prevents inadvertent ingestion and removes residual chemicals before they are absorbed through the skin.

Use skin creams after washing to replace protective oils that solvents strip away. Contaminated clothing should also be changed and laundered after working with solvents. Proper handwashing limits prolonged solvent exposure that adds up over time.

18. Educate and Train Users

Anyone handling solvents should understand proper safety protocols before use. Provide SDS hazard information, standard operating procedures, PPE training, and safe handling instruction. Limit solvent use to only trained personnel, not casual users unaware of the dangers.

Ensure sufficient oversight and reminders about ventilation, no smoking, bonding and grounding, fire prevention, and other safe practices. Proper training and education help reinforce good solvent handling habits that prevent accidents and health issues.
