Laboratory Safety

Laboratory Safety should come naturally and become your habit. Remember you are responsible for your own safety as well as safety of others working around you. Specially DEEE contains a wide variety of electrically-powered equipment including power supplies, motors, and testing and monitoring equipment. These and all electrical devices used in the lab setting present a potential danger of injury due to electric shock, fires due to wrongly connected experimental setups or due to sparks serving as an ignition source. A little care and adherence to prescribed safety guidelines will help avoid laboratory mishaps. Laboratory hazards should not scare you as the practical/real experiments can be both challenging and exciting because you get handson experience and set of skills necessary for your future.

Students, Insrtructors, Lab attendants and staff can protect themselves from the hazards of electricity by following some basic guidelines. The guidelines include maintaining awareness of the condition of lab equipment, the proper use of lab equipment and safe working practices.




Proper grounding and use of circuit protection devices.
All unprotected electrical connections and installations are insulated to prevent any damage.
Using originally rated fuses to replace blown fuses.
Do not use extension codes or multi plugs for connecting appliances that overload the rating of plug bases.
Avoid contact with energized electrical circuits.
Use guarding around exposed circuits and sources of live electricity.
Disconnect the power source before servicing or repairing electrical equipment.



Use of Material Safety Data Sheet (MSDS) for placing and storing chemicals accordingly.
Expired and used chemicals are disposed properly and safely.
Proper chemical labeling is done.
Performing routing lab cleaning.
Wear protective goggles and clothing during experiments.
Good housekeeping.



Fire extinguishers are placed 1.2m above the ground to ease the handling in a fire situation.
Existing Fire extinguishers are tested for its operation.
Fire extinguishers are placed in such a way that anyone can see it clearly from a distance and use it properly.
Type and use of fire extinguisher is mentioned and put in a color coded areas.
Maintaining electrical wiring in good condition.
Use extension cords for temporary use only.
Limit quantities of flammable liquids in laboratories.



Fire Exits are marked and unlocked 
Keeping clear pathways, so in an emergency to ease the evacuation.
Fire Exit doors are marked, unlocked (open from inside) and be opened outward.
Activate the nearest fire alarm, if not automatic.

Safety Procedures and Guidlines

Department has developed safety procedures and guidlines, for each and every laboratory, to be used and followed by the users. Procedures involved visual inspections, electrical tests and other checks that should be carried out by a Technical Officer. There is also a Faculty appointed Safety Officer (Mr. W.D. Kularatna), a department non-academic member, for overall coordination of health and safety issues. Above guidlines are not only for electrical safety but also for chemical, thermal, mechanical, EMC and radiation safety as well.
