This page and the idea of safety is provision for the reduction of accidents that happen in science. There are many experiments to do in science, while there is a safe method to doing all these there will of course be hazards and risks. To be aware of these hazards and the method of dealing with them should they occur is the best way for you to keep 10 fingers, your hair and your general being well.

Rules for your Safety

  1. Note the Fire Exits in the laboratory.
  2. Note the Emergency Stop Switches for Gas and Electricity
  3. Always leave your coat and bags out of the passage ways in the classroom.
  4. Report all Injuries, breakages and hazards
  5. Never eat, drink in the Laboratory
  6. Never disturb others experiments
  7. If Eye protection is requested it is not optional.
  8. Wash hands often, use gloves if required.

First Homework, go through the Lab Rules in your Journal

when you are clear on them sign the statement below

get your Guardian to read them and then sign them too.

First Aid Procedures

  • If anything gets in your eye, wash it out with a wash bottle.
  • If you have cut yourself, apply pressure to the spot with a clean towel, then cover it with a plaster.
  • If you burn yourself run your burned skin under a cold tap

  1. Identify the 35 risks in the Mayhem Lab
  2. Colour in the picture to draw attention to these Hazards

Senior Cycle Students should carry out the following free safety course

How to light a Bunsen Burner

How to carry out a Risk Assessment

Top Ten Dangers in the Lab

1.1. Hydrochloric acid -corrosive

2. Sodium Hydroxide -corrosive

3. Iodine -irritant

4. Mercury -poisonous

5. Copper sulphate -harmful

6. Hydrogen peroxide -corrosive

7. Sodium -very reactive stored under oil

8. Benedict’s solution -irritant

9. Methylated spirits -flammable

10. Cobalt chloride solution -toxic

never heat water in a microwave

Before running an experiment you should carry out a Risk Assessment. Heres an example

Experiment Title: To Show Liquids Expand On Heating

Date: Mon 18th Sept 2007

Possible Risks: burn from the Bunsen or hot liquid, cut from the glass wear

How might these occur: Messing not paying attention

Possible Prevention: Wear lab coat, put on goggles, tie back hair & clear your workbench.

Report any and ALL unsafe conditions you may find in your work area to your Teacher.

REMEMBER: Safety is a team effort!

Remember to use to the emergency switches,

these knocks off the gas and/or electricity in the room,

if there is a fire or other danger HIT THESE MUSHROOM BUTTONS
