© Imperial College LondonPage 4 Safety in the Laboratory BEHAVIOUR IN THE LABORATORIES A tidy lab is essential for a safe working environment. Keep all work areas free from clutter. Do not block passageways with bags etc. Eating and drinking in the labs is forbidden. Do not put on make-up or use phones or MP3 players. Students are only allowed in the labs from 2-5pm.

Hazardous substances are those classified as: Toxic, Harmful, Irritant, or Corrosive Any substance with a Workplace Exposure Limit Dust and bacteria of any kind, or Anything else which may be hazardous to health

© Imperial College LondonPage 6 Safety in the Laboratory A risk assessment identifies the hazards inherent in the substance and estimates the likelihood that it will cause harm. RISK = HAZARD x LIKELIHOOD OF EXPOSURE A COSHH assessment has been made on all the chemicals that you will use Make sure that you understand the hazards and any control measures that are necessary and follow them

© Imperial College LondonPage 7 Safety in the Laboratory PROTECTIVE CLOTHING Protective clothing is provided for you to wear Make sure that you follow the instructions ALWAYS wear your lab coat and eye protection when working in the labs or the pilot plant. ALWAYS wear a hard hat in the pilot plant laboratory You will be given instructions about when to wear gloves or ear-defenders.

If you spill or drop chemicals inform the technician. NEVER put waste chemicals down the sink. ALWAYS put them in the appropriate waste container. If in doubt ask the technician or demonstrator.

Avoid putting your head inside the fume-cupboard if at all possible. Try to work with only your hands inside the cupboard. Before you start work make sure that the fume cupboard is working If in doubt ask the technician.

Ensure that you protect your hands and face from splashes Wear appropriate gloves and face protection Do not touch the heating surface of a hot-plate or heater unless you are sure that it is cold. ALWAYS keep flammable materials or solvents away from ignition sources e.g. heaters or electric motors.
