Explanation:
Learn about emergency responses
You need to be familiar with what to do in case of an accident and whom to report to or contact. It is imperative to know where items like fire extinguishers, emergency showers, eyewash faucets, first aid kits, and fire blankets are stored and how to operate or use them. Ensure all accidents, however minor is reported to your supervisor.
2. Train before experimentation
Do not operate any equipment or conduct experiments without prior training.
If you are still unsure of a certain procedure, get help from your supervisor or any other trained staff. Write down protocols or make copies of the SOPs to refer to when in doubt.
3. Plan your work during normal working hours
This ensures that you are not alone for prolonged periods because working alone leaves you more vulnerable in case of accidents or injuries. Having other members around you also ensures you have extra pairs of eyes to point out potential risks that you might miss while performing your experiments.
4. Treat all chemicals in the lab as if they were toxic
This means that there should be no direct sniffing, touching or tasting of chemicals or reaction mixes. In addition:
Mouth pipetting is dangerous, so, use rubber bulbs or electronic pipette pumps to suck liquids,
When using volatile or toxic chemicals, ensure to open and use them within a fume chamber.
At the end of your experiments, thoroughly wash your hands with soap and clean water.
5. Adhere to electrical safety guidelines
Malfunction of sockets or equipment can lead to injury from electric shocks and damage of lab from fires, therefore:
Avoid the use of electrical extension cords and plugs with exposed or frayed wires.
In case a machine causes electric shock, immediately shut down the power source and report this to the supervisor or technician in charge.
Ensure that power sources are not overloaded because a lot of equipment can cause overheating of the socket which can lead to a fire.
6. Laser use safety guidelines
Safety guidelines depend on the classification of the laser, with high powered laser requiring more safety measures. Generally, consider the following:
Protective eyewear is required when working with lasers of class IIIa, IIIb and IV to avoid injury to the lenses.
Ensure reflective objects like mirrors and jewelry are removed because they can redirect the laser trajectory and bounce it off to skin or a flammable object.
Always switch on the laser warning light to warn other lab members against entering the room without the appropriate PPE.
Do not put the laser beam at eye level even when you think the laser is shut off.
Chemical Safety Rules and Guidelines
Chemistry labs have an assortment of chemicals and reagents that range from the very toxic to generally innocuous chemicals. Fatal and harmful accidents can result from careless handling or non-compliance to rules and guidelines. The following guidelines apply;
