The problem
A type of mineral fibre called asbestos is present in the building material of many older Region of Peel schools. This fibre needs to be removed because it is an odourless and tasteless product that when breathed in, can cause serious health problems such as mesothelioma, a fatal cancer that affects the lungs, as well as other lung-related diseases. Unfortunately, many cash-strapped schools in Canada are following Health Canada’s ruling that asbestos is safe when contained. That means that if the product is in good shape, there is no need to remove it. However, many countries disagree with this, including Britain, Australia, Japan, Sweden, Germany and Denmark; all of which have gotten rid of asbestos completely. Two sides to the story
Asbestos was very common before 1985, which is why all the schools made before that time likely have it in their construction. There is a big debate on whether or not it will be banned completely and both sides of this discussion have many good points.

This is why they think it would be better to leave the product alone and not remove it. Spokesperson Carla Pereira told the News that asbestos should often not be a concern as long as it is maintained properly. “It’s important to understand that the presence of asbestos in our schools is not a health risk. Health concerns only arise if asbestos is crumbled or pulverized,” said Pereira. This means that in its regular state, asbestos is harmless, but once it is crumbled into finer pieces capable of being breathed in, it is very dangerous. Health Canada has made several steps in trying to fix this situation, such as giving teachers, students, and faculty safety lessons on avoiding
From the perspective of a volunteer firefighter I feel that even though safety guidelines and personal protective equipment (PPE) are in place, exposure to carcinogens in the work place is too high especially in the fire service. Firefighters are public emergency workers with specialized training in firefighting and rescue. Firefighter’s primary job is to extinguish fires that are threatening property or civilians. However In recent years there has been an increase to the rescuer side. When a firefighter is on the job they face exposure to dust containing cement, fibreglass, asbestos, lead, and fumes containing hydrocarbons, and PCB’s which are all released from burning buildings. They are also exposed to toxic fumes, from using fuel in equipment and diesel fumes from apparatus. Firefighters are protected by wearing the proper PPE which includes a thermal protective jacket, pants, rubber boots balaclava, and self contained breathing apparatus and by the standards set out by the National Fire Protection Association (NFPA).
In this day and age where school administrators consider backpacks, lockers, and baggy pants to be potential dangers to students and faculty, what will be next? Perhaps pencils, pens, scissors, and glue will be added to the list of items to ban from schools. These, along with other hazardous educational necessities pose real threats to maintaining an orderly school and should be prohibited.
Radon is formed as one part in the radioactive decay chains of thorium and uranium as they decay into lead. As radon decays, it produces decay products. These products stick to things in the air like dust particles. If these dust particles are inhaled the can stick to ones lungs and cause lung cancer. Several studies have proven that those who breathe in radon gas are more likely to have lung cancer than those who don’t. This therefore makes radon a considerable hazard in workplaces such as mechanic shops and ship yards. Radon poisoning comes in second to lives claimed from lung cancer only to cigarette smoking.
sealed areas already dangerous to human beings, instead of simply when it might be used as insulation in a ventilated area, or other similar cases which actually expose it to people against their will. ---------------------------------------------------------------------- Where asbestos has been banned, its roles must be taken by products which are often either inferior, or far more expensive. This has a negative impact on society as a whole, which (especially if the previous arguments are true in whole or part) may be greater than the benefit of its removal. In fact, as with DDT and CFCs, some of the promotion of the ban has been financed by the very companies which sell more expensive or less effective alternatives, leading to an ironic charge of corporate greed as the motivation behind environmental concerns.
Lung cancer dates back to 1761 when it was called disease. In 1878 only 1% of the populations were thought to have it. When the 1900s came by that number rose to 15%. There was only 374 case filed by 1912. It wasn’t until 1929 when smoking became a factor in lung cancer. Fritz Lickint was the first person to tell the public about the dangers of smoking that which went into a campaign act to tell worldwide about the dangers of smoking.
Each year about 3,000 nonsmoking adults die of lung cancer as a result breathing the sm...
... in inhabitants living close to smelters and arsenical chemical factories. Citizens who live near waste sites with arsenic may have an increased risk of lung cancer as well.
Asbestos is a group of silicate minerals that is now a known carcinogen. However, it was once used in a variety of construction materials, including insulation and pipe wrappings, due to
The collapse of the World Trade Center caused a toxic dust cloud that covered parts of Manhattan and Brooklyn. Several of these toxins can cause alterations in the cell that may eventually cause lung cancer including the toxins explained in this paper. Each of these three chemicals are known to cause lung cancer through aerosol exposure. The concentration of the chemicals and the length of the exposure of these chemicals affect the risk of being diagnosed with lung cancer. As stated previously, several of these toxins had exposures over the regulation limit from the collapse of the World Trade Center. There are few studies on the effects of the World Trade Center dust because of how relatively recent this event occurred. Since lung cancer is
Would anybody want their freedom taken from them? Nobody would willingly give their freedom up. What’s the next thing thats going to happen, will schools having edible food. Hard to see, right? So are uniforms. Schools should not have uniforms for these three reasons: It takes the students freedom of expression away, it’s a bandaid reason to cover up violence, and some parents might not be able to afford the uniforms.
A worker's lungs may react more severely to silica sand that has been freshly fractured (sawed, hammered, or treated in a way that produces airborne dust) [Vallyathan et al. 1988]. This factor may contribute to the development of acute and accelerated forms of silicosis.

Hazardous materials come in many forms and include: explosives, flammable and combustible substances, poisons and radioactive materials. These dangerous substances are usually released during a transportation accident or through accidents or chemical spills in plants and factories. Since hazardous materials are shipped or transported through a variety of ways including l, waterways, and major highways and the release of these chemicals could cause serious harm. They can enter our water ways from oil rig spills or enter the environment from a train derailment or a container truck accident. The affects of a hazardous materials incident can include serious injury or death, serious health effects and property damage and environmental damage including bodies of water.
Thousands of people are affected by the lack of school safety in schools across the nation. Students everywhere are attending schools that are more dangerous than expected. This is a growing concern everywhere, and schools need to improve, or else they are prone to being unsafe. Whether it is building, drill, concussion, social, or technology safety, schools need to improve to lower the risk of an incident.
Children should be ensured of a safe learning environment as school is the place where they spend most of their day. Well disciplined schools emphasize on the importance of learning and intolerance of conditions which ...
