Hazard Signs
Talk from Mr. Ellis
Mr Ellis has five job titles, but he is only paid for one. The five job roles are Senior Science Technician, Department Safety Officer, School Radiation Protection Officer, Electrical Safety Officer and One of the School First Aider which is the only job role he gets paid for. The qualifications required to become a technician you must have 4 GCSE’s in Science, English and Maths. Also, you must have the Higher National Certificate in Science and there are a number of short courses you must take part in. A brief description of Mr. Ellis’ role in the school is that he is the Lab Maintenance Officer, person in-charge of ordering equipment, person who advises staff on experiments, especially safety. Also, he is in-charge of manufacturing equipment, storing chemicals/radio active materials and testing safety of electrical equipment.
The laws relating to safety in the Lab is the Health and Safety Work Act, Disposal of Hazardous waste regulations, First Aid work regulations, Fire Safety Regulation – Fire Extinguishing and the Education Act – Pupil not allowed in Lab without staff. To get rid of chemicals, it must be poured down the drain or dumped in foul water drains. But some chemicals need specialise disposal teams. COSHH stands for Control of Substances Hazardous to Health and CLEAPS stands for Consutitum of Local Education Authorities for Safety Science. Teachers know how to handle some chemicals because Hazards guidance notes and the Royal Society to Chemistry handbook. Fume cupboard is a large piece of scientific equipment common to chemistry laboratories designed to limit a person's exposure to hazardous and/or unpleasant fumes. To use radioactive sources safely, you must have a Science Degree, a short course which lasts for 1 hour and training.
Talk from Sally Skelly
To become a First Aider, you must have interest in helping people and you must go on a training course with British Red Cross which lasts for 4 days. At the end of the course, there is an exam on a scenario that you must explain how you would treat. There are four First Aiders in Archbishop Tenisons School. They are Lou Mitchell (First in command), Dona Harris, Sally Skelly and Bob Ellis. A first aid box contains plasters, bandages, thermometers, anti-septic wipes, sterilised eye dressing, safety pins, scissors, twissers, painkillers and more. The only situation where you can’t treat a person is when the situation will cause a problem for yourself. As soon as you arrive at a scene you must check for damage. An accident book is a book where you record information about an accident. In the book you record the name of the person, time of the incident, date and location of the incident. In the school, the parents/guardian of blue blazers has to be contacted, so that the school has permission to give the child paracetamol. But for black blazers, permission from parents/guardians is not required. When someone has been burnt by an acid, it must be watered for a least 20mins and to treat a fire burn it must be watered for a least 10mins and you must use a sterilized dressing over the wound. If someone has glass in their hand, they must raise their hand above their heart to reduce lose of blood, apply pressure to either side, loosely bandage over it or take the person to hospital.
If we find a person unconscious we must:
- check for response,
- shake the shoulder of the person,
- shout for help if there isn’t any response from the patient,
- open the air waves
- look for chest movement
- Put one hand on the casualties head; tilt their head back and one hand on the chin to check if the casualty is breathing.
Fire Triangle
The fire triangle is made up of oxygen, heat and fuel. A fire can be prevented if one of them is removed. Without the fuel, the fire would stop. Without enough heat, the fire cannot continue and without enough oxygen, the fire cannot begin. Oxygen can be removed from a fire by smothering it with aqueous foam.
In and around room 22, there are different things to help, stop or fight a fire. There are different fire extinguishers for different types of fires. There are also fire blankets which are used to extinguish starting fires and fire sand buckets which are used to put out fires. There is also a gas emergency valve which needs a key to turn it on, but it just has to be pushed in for it to be turned off. There is a fire emergency alarm just outside the room just in case there is a fire.
In the school, every form class has a fire assembly station around the back of the school, where they have to be once the fire alarm has gone off. For each form class to know there fire assembly station, there is an A4 sign in each classroom, informing the fire assembly station and what to do when the fire drill goes off. There are 3 main exits that you must exit out of when a fire alarm has gone off, depending on what side of the building you are on. If you are on the right side of the building, you will have to exit at the main entrance, if you are in the middle of the building, you must exit at the door that leads to the playground and if you are on the left side of the school including the link corridors, you must exit at the door on the ground floor link corridor.
Fire Extinguishers
Water – The water fire extinguisher didn’t have a colour except for the colour of the tank which was red and white. The class of fire which water is, is class A. The water fire extinguisher works by holding it upright, pulling put the pin, then aiming at the base of the fire from a minimum distance of 1 metre and squeezing the lever. The water fire extinguisher is suitable for on paper, wood textiles.
Foam – The colour code of the foam fire extinguisher is yellow. The class of fire which foam is, is A and B. The foam fire extinguisher works by holding it upright, pulling put the pin, then aiming at the base of the fire from a minimum distance of 1 metre and squeezing the lever. The foam fire extinguisher is suitable for paper, wood and textiles and flammable liquids and gases.
Carbon Dioxide – The colour code of the carbon dioxide fire extinguisher is black. The carbon dioxide fire extinguisher is in class B. The carbon dioxide fire extinguisher works by holding it upright, pulling put the pin, directing the horn and aiming at the base of the fire from a minimum distance of 1 metre and squeezing the lever. The carbon dioxide fire extinguisher is suitable for flammable liquids and gases and electrical hazards.
Dry Powder - The colour code of the dry powder fire extinguisher is blue. The dry powder fire extinguisher is in class A, B and C. The dry powder fire extinguisher works by holding it upright, pulling put the pin, directing the horn and aiming at the base of the fire from a minimum distance of 1 metre and squeezing the lever. This fire extinguisher is suitable for paper, wood and textiles, flammable liquids and gases and electrical hazards.
Vaporising Liquid – The vaporising liquid fire extinguisher doesn’t have a colour code. But this fire extinguisher is in class A. The vaporising liquid fire extinguisher works by holding it upright, pulling put the pin, directing the horn and aiming at the base of the fire from a minimum distance of 1 metre and squeezing the lever. This fire extinguisher is only suitable for the group of paper, wood and textiles.
Fire Buckets
Fire buckets contain sand which is used to put out fires. Fire buckets are mostly kept in area where a fire is likely to occur. For the fire to be put out, the sand in the bucket is poured over the fire to starve it from the oxygen it needs to stay alight. Fire buckets can also absorb spills of flammable liquids to make them less dangerous.
Fire Blankets
Fire blankets are used to extinguish starting fires. Fire blankets are places over a fire to smother it. The size of fire blankets determined the location. For instants, small fire blankets are used in kitchens and around the home. These fire blankets are normally made out of fibreglass.
But large fire blankets are used in laboratories and industrial places. There large fire blankets are normally made out of wool. The job of a fire blanket is to cut off the oxygen supply to the fire, and put it out.
Sprinkler Systems
The sprinkler Systems is a fire protection measure, which consists of water and is activated when there is a sign of a fire. A sprinkler head will spray water into the room if sufficient heat reaches the bulb and causes it to shatter. Sprinkler heads operate individually. Not everyone has the sprinkler systems because it can result in property lose and building interruptions.
Fire Doors
A fire door is a type of door that once fire/smoke is detected, the doors will automatically shut (not lock) to barrier and prevent the fire/smoke which contains dangerous chemicals from spreading around the premises. All fire doors have a luminous sign – which can be seen it the dark (as seen below) on it.
Fire doors are made of a combination of materials, such as:
- timber
- steel
- gypsum
- vermiculite-boards
Fire Drill
A fire drill is a practising method for evacuating a building for fire or other emergencies. Normally, the fire alarm goes off and the building is everyone has evacuated the building as if a real fire has occurred. The Department for Education and skills requires a school to have a fire drill at least once every academic year. In some schools, form classes all have a fire assembly point somewhere in or around the school where they must be based during a fire drill or an actual fire for a register to be taken, to make sure that know one is still left or trapped inside the building.
