Information About Chemical Spills .

I Have Written About Chemical Spills In This PPT, How To Prevent Them And Their Types.

1. SPILLS CHEMICAL

2. CHEMICAL SPILLS ARE THE UNCONTROLLED RELEASE OF A HAZARDOUS CHEMICAL, EITHER AS A SOLID, LIQUID OR GAS. CHEMICAL SPILLS

3. CHEMICAL SPILLS Chemical spills can result in chemical exposures and contaminations. These spills need to be minimized as much as possible. If a chemical spill should occur, a quick response with a stocked chemical spill kit will help minimize potential harm to personnel, equipment and laboratory space. Another thing to consider is the safety of the individual handling the chemicals and how to react if something occurs.

4. CAUSES Causes of chemical spills can be natural or human-caused. Natural causes include earthquakes, hurricanes, fires and volcanic eruptions. Human-caused events include industrial accidents or unsafe handling, improper storage, failure of storage containers and improper disposal.

5. HOW TO PREVENT CHEMICAL SPILLS Place chemical containers being used in a hood or lab bench area that reduces the possibility of accidentally knocking over a container. Keep all unused reagents in their appropriate storage area and keep your work area clean of needles equipment and clutter. Plan your movements. Look where you are reaching to ensure you will not cause a spill. Avoid transporting chemicals from the stockroom during periods of high traffic in hallways. Transport chemical containers in a chemical carrier or cart. Place absorbent plastic-backed liners on benchtops or in fume hoods where spills can be anticipated. For volumes of liquid larger than what can be absorbed by liners, use trays.

6. CLEAN UP Chemical spills can result in chemical exposures and contaminations. Whether a chemical spill can be safely cleaned up by laboratory staff depends on multiple factors including the hazards of the chemicals spilt, the size of the spill, the presence of incompatible materials, and whether you have adequate training and supplies to safely clean up the spill. DO NOT enter the area if you cannot assess the conditions of the environment well enough to be sure of your safety.

7. TYPES 1. Small Spill 2. Large Spill Small chemical spills of low toxicity which do not present the potential for overexposure or a significant inhalation hazard by being volatile or dust can generally be safe to clean up by laboratory personnel. A small spill is generally a spill involving a chemical that is not highly toxic, does not present a significant fire or environmental hazard, and is not in a public area such as a common hallway. Large chemical spills include spills of any quantity of highly toxic chemicals or chemicals in public areas or adjacent to drains. Large spills require emergency response.
