PREVENTION Never work alone with high voltage. Have a partner who knows how to disconnect the power and who knows CPR. A healthy person can be easily restarted after electrocution. High voltages per se dont kill, but they cause dangerous currents to flow. Rule of thumb: 1 mA (milli Ampere, or 0.001 Amps) is startling, 10 mA is painful, 100 mA can cause the heart to go into fibrillation or stop. An old electricians trick to avoid accidental passage of electricity through the heart is to work with one hand and keep the other hand in a pocket. IN CASE OF ELECTROCUTION

PREVENTION Poisons must be stored in a safe location and in a labeled container.
IN CASE OF POISONING Keep Calm
BEFORE CALLING FOR HELP: Poisonous Fumes or Gases
Poisons on the skin
Poisons in the Eye
Swallowed Poisons/Medications
CALLING FOR HELP:
HOW TO INDUCE VOMITING The most important item to have in your home when poisoning occurs is Ipecac syrup. Ipecac is a plant extract that when swallowed causes vomiting. Vomiting will remove the poison from the stomach. Your doctor or Poison Control Center may not always recommend using Ipecac syrup. Do not use Ipecac without the advice of a doctor or the Poison Control Center. Remember: Never produce vomiting unless instructed to do so! Never produce vomiting if the patient:
If you are instructed to use Ipecac Syrup to produce vomiting: Give one tablespoonful (15cc) to young children 1 to 12 years of age, and two tablespoonfuls (30cc) to older children and adults. Always consult with your doctor or the Poison Control Center before giving Ipecac syrup to a child under the age of 1.

PCB oils have excellent dielectric properties, stability and are non-flammable and were used in manufacture of certain high voltage transformers, capacitors and other devices. PCBs were developed in the late 1940s and since the mid 1970s manufacturers have phased them out due to toxicity. Newer oil filled High Voltage components will be labeled PCB-free. PCB oils are NASTY BAD STUFF for living beings. If you suspect an old component uses PCB oils, you can call the EPA or hire a test lab, or CAREFULLY do the following three simple tests for PCBs :
Mineral oils lack the strong odor, will float in water, and burn yellow. If PCBs are present, the component, the oil, and anything contaminated should be considered TOXIC. Protect the skin from contact. Wrap the component in absorbent material and place in a plastic bag, along with any waste wiping materials. Wash thoroughly. Symptoms of PCB poisoning include fatigue, headache, cough, numbness in the arms and legs, discharge from the eyes, and unusual skin sores. Long term effects include liver and kidney damage and birth defects. Treatment is to avoid exposure. For more info see Safety Bulletin 37 from the University of North London |

Magnets can damage credit cards and computer disks. Extremely strong magnets can be dangerous ! PREVENTION Even the most powerful magnetic fields ever produced cause no direct harm to living beings. However powerful magnets can exert dangerous forces on objects. Ferrous metal objects can pose a danger near high powered magnets, such as a magnetic resonance imaging (MRI) unit because the maagnet draws magnetic objects to it. Flying items can hurt and kill, including a young boy who died in 2001 from injuries after a metal oxygen tank was brought into an MRI unit, flew toward the magnet, and struck him in the head.
Strong permanent magnets can attract and snap together with sudden unexpected force, pinching hands or body parts. Magnets can erase credit cards, computer floppy disks and hard drives. IN CASE OF EXPOSURE Magnetic fields cause no direct harm to living beings.

Lasers are classified to describe the capabilities of a laser system to produce injury to personnel. This classification rates from Class I lasers (no harm) to Class IV lasers (let's cut thick steel). The manufacturer is required to label Class II, III and IV lasers with a warning label which has the laser's classification printed on it. Class I lasers are low powered devices that are considered safe from all potential hazards. Some examples of Class I laser use are: laser printers, CD players, CD ROM devices, geological survey equipment and laboratory analytical equipment. No individual, regardless of exposure conditions to the eyes or skin, would be expected to be injured by a Class I laser. No safety requirements are needed to use Class I laser devices. Class II lasers are low power (< 1mW), visible light lasers that could possibly cause damage to a person's eyes. Some examples of Class II laser use are: classroom demonstrations, low power laser pointers, aiming devices and range finding equipment. If class II laser beams are directly viewed for long periods of time (i.e. > 15 minutes) damage to the eyes could result. Avoid looking into a Class II laser beam or pointing a Class II laser beam into another person's eyes. Avoid viewing Class II laser beams with telescopic devices. Realize that the bright light of a Class II laser beam into your eyes will cause a normal reaction to look away or close your eyes. This response is expected to protect you from Class II laser damage to the eyes. Class IIIa lasers are continuous wave, intermediate power (1-5 mW) devices. Some examples of Class IIIa laser uses are the same as Class II lasers with the most popular uses being laser pointers and laser scanners. Direct viewing of the Class IIIa laser beam could be hazardous to the eyes. Do not view the Class IIIa laser beam directly. Do not point a Class IIIa laser beam into another persons eyes. Do not view a Class IIIa laser beam with telescopic devices; this magnifies the problem. Class IIIb lasers are intermediate power (c.w. 5-500 mW or pulsed 10 J/cm²) devices. Some examples of Class IIIb laser uses are spectrometry, stereolithography, and entertainment light shows. Some "super" laser pointers are in this class. Direct viewing of the Class IIIb laser beam is hazardous to the eye and diffuse reflections of the beam can also be hazardous to the eye. Do not view the Class IIIb laser beam directly. Do not view a Class IIIb laser beam with telescopic devices; this magnifies the problem. Whenever in a laser controlled area, wear the proper eye protection. Class IV lasers are high power (c.w. >500mW or pulsed >10J/cm²) devices. Some examples of Class IV laser use are surgery, research, drilling, cutting, welding, and micromachining. The direct beam and diffuse reflections from Class IV lasers are hazardous to the eyes and skin. Class IV laser devices can also be a fire hazard. Much greater controls are required to ensure the safe operation of this class of laser devices. Whenever occupying a laser controlled area, wear the proper eye protection. Most laser eye injuries occur from reflected beams of class IV laser light, so keep all reflective materials away from the beam. Do not place your hand or any other body part into the class IV laser beam. The pain and smell of burned flesh will let you know if this happens. Realize the dangers involved in the use of Class IV lasers and please use common sense. |

Ignoring this Warning can hurt or kill you ! You could be hurt. You could die. Do not attempt these experiments or projects unless you fully understand and accept all risks involved. Minors should not perform experiments on this web site without supervision of a parent or teacher. BEFORE starting any experiment, all persons should know and completely understand these warnings, as well as warning labels on all materials and items used. If working with experimental hazards, print, review and post safety information. For example before performing an experiment involving two hazards, electricity and battery acid, everyone in the group or class must read and understand these two hazards, have safety materials on hand, be ready to act, and have the hazards printed out and posted in a prominent place such as by the telephone. |
