xplosive Ordnance Disposal (EOD) Bomb Technicians. Their job is to limit damage to people and property by rendering safe or disposing of unexploded, unfired or fired ordnance (Conventional, nuclear, chemical, biological, and radiological). They respond to IED’s, UXO’s (unexploded ordnance) from wars past, clear bombing ranges and much more. Composition C Composition C (C4) is the standard HE (high explosive) for the military. One block of M112 C4 weighs 1.25 pounds and has a TNT equivalent…

MEMO TO: Robert Walton, CEO FROM: James Babson, Organization Health and Safety Officer DATE: 16 September, 2016 SUBJECT: Summary of Work Safe BC’s report on Babine Sawmill explosion Executive Summary The explosion at the Babine Forest Products sawmill in Burns Lake on 20 January 2012 was caused by the ignition of wood dust accumulated between the belt and sheaves of the 8R-25 conveyer. Due to confinement by the guard and large presence of wood dust in the air, the fire changed into a…

necessary areas throughout the plant. The Port Wentworth plant takes raw sugar cane and creates sugar, powdered sugar, brown sugar, and numerous sugar products. This seemingly harmful food turned deadly when it was mishandled creating a series of explosions killing fourteen employees and injuring thirty-six additional employees. (Board) My goal…

About 542 million years ago, an event known as 'The Cambrian Explosion' also known as 'Cambrian Radiation' occurred. It began in the Cambrian period which took place during the Paleozoic Era 542-251 million years ago. It is one of the most significant episodes in the history of life (Conway Morris, 2006). The Cambrian Explosion changed everything. Prior to the Cambrian Explosion, large animals were soft-bodied. Palaeontologists discovered fossils which accounted for approximately half of all…

The Cambrian explosion is perhaps one of the most impactful events in evolutionary history, it gives way to present day animals in fossilized forms which we now use to understand a time period that was much more complex. The period occurred 535-525 million years ago, and was a time where the majority of animals were soft bodied and appeared to be grazers, suspension feeders as well as scavengers. The Cambrian explosion occurred and with it extinctions of many of the soft bodied animals. Those…

Scientists estimate that the Cambrian explosion lasted for as little as 5 to 10 million years. That’s very brief in the earth’s history. This chapter focused on the nature of the Cambrian explosion and how it challenged what the traditional concept for earth’s history was. Mammals make up a very, very small percent of life on earth. While the current geological…

Paleozoic The big incident of this era is the Cambrian explosion that happened 540 million years ago. Mesozoic Angiosperms were diversified during this era Cenozoic Mammals increase in size 2. Define/explain the following terms: Ediacaran, diagenesis, stromatolite, permineralized, Cambrian explosion, trace fossil, index fossil  The Ediacaran Period (pronunciation: Spans…

The Cambrian Period was an era filled with a massive explosion of a variety of animals and ecosystems. It was a time where super continent Pannotia no longer existed. During this time period, North America remained above water and was eroded by running water. North American was also on the equator which meant warm climate. The continents were oriented very differently, the east coast of North America faced the south. Activities such as transgression of the sea, and carbonate deposition went on…

Big History has produced many themes within in context, with the most prominent being complexity. However, expansion can also be seen as the most important theme that traverses through the Big History story. Expansion can be seen in at the very beginning with the Big Bang, through the increasing expanding universe that we live in today, it can also be seen in the creation and development of our stars and planets. Furthermore, expansion allows for the many diverse and different organism alive on…

A long, long, long time ago, approximately 3.5-39 billion years ago the very first living organisms appeared on Earth1. During the Cambrian Period/Explosion the first true diversification occurred on Earth. Prior to this point there was still no vegetation and the oceans had yet to be oxygenated. It is believed that a reduction in the oxygen depleting bacteria lead to the oxygenation of the oceans which lead to the development of hard shelled organisms and an increase in invertebrates as well as…
