General Safety Tips, General Precautions 1. Substitution
Substituting safe materials for more hazardous ones is the most effective precaution. General rules include:
a. Always choose water based or latex paints and other products over solvent containing ones whenever possible
b. If solvents must be used, Material Safety Data Sheets can be used to choose the least toxic ones.
c. Choose products that do not create dusts and mists. Avoid materials in powder form or aerosol products.
d. Avoid products containing cancer causing chemicals whenever possible.
2. Personal Hygiene
Practicing good hygiene in the studio is one of the simplest and least practiced ways to avoid exposure to toxic substances.
a. Never eat, drink or smoke in studios and other environments where there are toxic materials. Dust settles in coffee cups, vapors can be absorbed by sandwiches, and hands can transfer substances to food and cigarettes. Cigarette smoking is especially hazardous because some substances inhaled through a cigarette can be converted by the heat to more hazardous forms.
b. Keep eating and living areas separate from working areas.
c. Wash your hands thoroughly after work, before eating, using the bathroom and applying make-up.
d. Wear special work clothes and remove them after work. If possible leave them in the workshop and wash them frequently and separately from other clothing.
e. Never use tuluene, turpentine, kerosene, or other solvents to remove paints, inks, or stains on your hands. If soap and water is inadequate, use baby oil or a waterless cleaner. Follow with soap and water and a lotion to prevent drying.
f. Before leaving studio, wash under you fingernails. Keep a nailbrush near your studio sink. Keep nails trim and clean; do not bite or pick nails.
g. Never hold brushes or tools in your teeth or mouth
h. To prevent mechanical accidents, recognize your physical, emotional and mental limits. Eat and sleep appropriately. Decreased alertness, often due to hunger or fatigue is a major cause of accidents.
i. Get an annual medical checkup with a physician trained to recognize work related health problems.
3. Keep studio clean and organized
Continuous, diligent monitoring and cleaning of the studio reduces the risk of accident and fire. Maximize hazard free space in the studio by designating a minimal area where potentially hazardous materials are used.
a. Do not use cleaning methods which raise dust. Wet mop floors followed by vacuuming, and sponge surfaces.
b. Have available the types of face, eye protection, gloves, wash-up facilities, and first aid equipment needed to clean up hazardous spills.
c. Clean up small liquid spills immediately. Wear protective clothing, especially gloves and a mask, when cleaning up toxic spills. If in an emergency, rags, sawdust or paper is used to mop up flammable spills, place soaked materials in a sealed fireproof container. Preferred cleaning materials include activated charcoal, diatomaceous earth, or cat litter (free of deodorizing chemicals). Once liquid has been absorbed by these nonflammable materials, dispose of them in a heavy-duty trash bag.
d. Keep the studio clean and free of hazards such as objects, debris, or wet, slippery floors. Trying to work on litter strewn tables reduces the effective control over tools and equipment, leading to careless actions. The most common circumstance to accidents is carelessness.
e. Properly stored tools remain in good condition longer. Maintain all equipment and tools in good working order.
f. Keep extension cords and hoses off the floor by coiling them onto a hook when not in use.
4. Ventilation Effective ventilation is essential to making art safely.
Ventilation is the primary environmental issue that affects artists who work with hazardous materials.
Poor ventilation means that toxic materials in the form of dusts, fumes, gases, mists, or vapors can be inhaled. Agents can be absorbed in nose and mouth, some get to the lungs, and a few are absorbed into the circulatory system. Additionally, the accumulation of vapors from flammable liquids can create a potentially explosive situation.
Appropriate ventilation provides protection for artists so that many art materials can be used without threat.
A common recommendation on product labels is USE ONLY WITH ADEQUATE VENTILATION. Such a nonspecific phrase is of little help.
A blowing rather than exhausting fan in the studio may reintroduce toxic chemicals into one's personal intake area instead of carrying them away. Taking work outdoors to be sprayed or blowing vapors out a window with a strategically place fan may not be sufficient. Airflow varies with wind, temperature and air pressure. In many instances, ceiling mounted down-draft or reversible fans do more to stir dusts, fumes and vapors into personal intake areas than to provide effective ventilation.
Some artists mistakenly believe that airborne substances they encounter are heavier than air, and are therefore found closer to the floor. However, floor fans can bring substantial quantities of undesirable substances to one's personal intake environment. To improve ventilation significantly, floor fans must effectively dilute or remove contaminated air from the workplace.
Fire Safety Fire hazards have been found to be the greatest problem in artist studios, particularly due to poor solvent storage.
1. Purchase in as small a quantity as possible. Although larger containers might b cheaper, having large quantities of flammable or combustible liquids around is a serious fire hazard.
2. Do not smoke or permit smoking in any studio containing flammable or combustible liquids. Flammable vapors can travel considerable distances, resulting in fire hazards in other parts of the studio.
3. Keep all sources of ignition away from flammable liquids. This includes flames, sparks, static electricity, hot metal surfaces and electric element.
4. When pouring flammable liquids from large metal drums into metal containers, connect the two metal containers together with wire to bond them. This prevents the build-up of static electricity, which can ignite the flammable liquids. The metal drum should also be grounded with a ground wire leading to a ground such as a tap or a radiator.
5. Store flammable or combustible solvents in safety cans. For dispensing small amounts of solvents, store the solvents in spring loaded dispensers.
6. Make sure all electrical equipment is in good repair and adequately grounded. All wiring and equipment should meet standards of the NFPA's electrical code.
7. Fans in local exhaust ventilation systems should have non sparking or nonferrous blades, and the motor and controls should be outside the path of the vapors or be explosion proof.
8. Do not use gas fired space heaters unless the heater is approved for use in the presence of flammable materials.
9. Waste flammable or combustible liquids should be stored in approved solvent disposal cans, while awaiting proper disposal.
10. Solvent soaked rags and paper should be stored in self closing oily waste cans or other closed metal containers. These should be emptied daily.
11. Do not store flammable or combustible liquids near escape routes from studios.
12. Keep a dry chemical or carbon dioxide fire extinguisher on hand for emergency use.
13. Clean up spills of flammable liquids immediately.
Storage of Art Materials 1. Clearly mark bottles, boxes, and storage containers as to their contents, hazards, and date received and opened.
2. Use marked, unbreakable containers whenever possible. Do not use food product containers. This prevents accidental ingestion of chemicals that do not have warning odors.
3. Keep all original or unbreakable containers tightly closed except when using them in order to prevent escape of dust or vapors.
4. Keep a current inventory of all materials on hand, their locations and date of purchase in order to dispose of materials with limited shelf life. Some chemicals even become explosive with age. Ideally, store materials in amounts that will be used within two months.
5. Purchase flammable or combustible materials in small quantities. Although larger containers might be cheaper, large quantities of these materials can be a serious fire hazard.
6. Post locations of flammable or highly toxic materials.
7. Apply good housekeeping. Have cleaning supplies for handling of spills on hand. If respiratory protection , gloves, or other personal protective equipment are needed, have these in the studios at all times.
8. If chemical corrosives or chemicals are stored, be prepared with an eye was station or emergency shower.
9. Have fire protection or extinguishers available which are approved for fires caused by the type of chemical stored.
10. Never store any material which you are not prepared to control or clean up if it spills.
11. Make safe storage and disposal an ongoing part of your work, with seasonal cleanings and reevaluations.
12. Organize storage wisely. Do not store large containers on high shelves. Never store hazardous chemicals directly on the floor or above shoulder height.
13. Store flammable or combustible solvents in fire safety cans. For dispensing small amounts of solvents, store the solvents in spring loaded dispensers.
14. Store chemicals that are highly toxic if ingested (for example, mercuric chloride and sodium cyanide) in a locked cabinet. Store flammable and combustible materials such as acetone, petroleum distillates, turpentine, and other solvents in specially designed OSHA-approved fireproof cabinets. Keep the cabinets closed; vent if required by local regulations. Explosion-proof refrigerators also decrease the risk of fire or explosion.
15. Store reactive chemicals separately and separate materials that may react if inadvertently mixed. For example, bleach mixed with acid or ammonia may create highly toxic potentially lethal gasses.
16. Do not dispense or mix chemicals in or near the storage area.
17. Ventilate the storage room. Keep it cool and keep chemicals out of direct sunlight.
18. Know your local regulations. Some areas limit the amount of hazardous materials, especially flammable solvents, that may be stored.
Disposal of Art Materials Purchase in as small a quantity as possible. Although larger containers might be cheaper on a per volume basis, having large quantities of toxic and flammable materials around is more of a hazard, and disposable of leftover amounts is a problem. Also, if an art materials in powdered form comes in a paper bag or sack, store the opened bag in a metal or plastic container with a lid. You can also empty the bag into the container.
Store rags in a metal fire-proof container, empty daily. Hang oily rags in a well ventilated area (outside). Another alternative is to place them in a pail of water. When dry dispose of in regular weekly garbage pick-up.
Aqueous liquids, such as acid and alkali solutions used in photography and printmaking, should be neutralized ( baking soda for acids; citric acid for alkalis) before they are slowly poured down the sink with lots of running water. Always dilute concentrated acids by pouring the acid into the water, never the reverse, to prevent the acid from splashing.
Organic solvents, such as turpentine and mineral spirits, should not be poured down the drain because they kill bacteria that break down other waste products. Some solvents can be recycled, which greatly reduces the amount to be disposed:
1) Slowly pour used or dirty solvents through fine steel mesh, or a coffee filter, inserted in a metal funnel and into a receiving can.
2) Cap and clearly label the container as to what it contains and when it was retrieved.
3) Package the dirty solvents and chemicals in the filter in a sealed container, and dispose of it through regular trash pick-up procedures.
For small quantities, such as less than a liter, let solvents evaporate. Prevent inhalation by placing evaporating solvents under a fume hood or outdoors where the material is secure from children.
For large quantities of solvents and solvent containing materials, contact your local fire department. Solvent soaked rags and papers should be put in a metal container. At the end of the day, hang them in a safe place outdoors to allow evaporation. Discard them them in a sealed, flame-proof container. Do not use plastic containers because many solvents will dissolve them.
If you are uncertain about what you can throw in the garbage, the best solution is to take materials/waste to Household Hazardous Waste.
Methods of Waste Disposal: There are a variety of methods of disposing of waste materials, including recycling, treatment, pouring it down the drain, evaporation, ordinary landfills, and taking it to Household Hazardous Waste. Some of these options do not apply to the most hazardous waste.
Recycling: Many waste art materials can be reused or used by someone else. Left-over art materials can be donated to an art center or secondary school. Hazardous materials should never be donated to an elementary school, and highly toxic materials like lead glazes should not be recycled. (see above on turpentine recycling)
Sewage System: Concentrations of copper and zinc ions, although not classified as hazardous waste, are controlled by sewer codes. Solvents should never be poured down the sink.
Landfill: Non hazardous solid waste materials can be placed in the regular trash for carting to a normal landfill. Some toxic materials can also be placed in the trash, including clay, metals, and paint residues. Glazed pottery can also be placed in the trash if it does not leach toxic metals.
Hazardous Waste Disposal:
Many communities now have household hazardous waste collection programs. See your county or city phone listings for a local collection site.
