Hierarchy Of Hazard Control
Hierarchy of hazard control is a system used in industry to prioritize possible interventions to minimize or eliminate exposure to hazard (risk), hazards. It is a widely accepted system promoted by numerous safety organizations. This concept is taught to Management, managers in industry, to be promoted as standard practice in the workplace. It has also been used to inform public policy, in fields such as Road traffic safety, road safety. Various illustrations are used to depict this system, most commonly a triangle. The hazard controls in the hierarchy are, in order of decreasing priority: * Hazard elimination, Elimination * Hazard substitution, Substitution * Engineering controls * Administrative controls * Personal protective equipment The system is not based on evidence of effectiveness; rather, it relies on whether the elimination of hazards is possible. Eliminating hazards allows workers to be free from the need to recognize and protect themselves against these dangers. Subst ...

Particle Size
Particle size is a notion introduced for comparing dimensions of solid particles ('' flecks''), liquid particles ('' droplets''), or gaseous particles ('' bubbles''). The notion of particle size applies to particles in colloids, in ecology, in granular material (whether airborne or not), and to particles that form a granular material (see also grain size). Measurement There are several methods for measuring particle size and particle size distribution. Some of them are based on light, other on ultrasound,Dukhin, A. S. and Goetz, P. J. ''Characterization of liquids, nano- and micro- particulates and porous bodies using Ultrasound'', Elsevier, 2017 or electric field, or gravity, or centrifugation. The use of sieves is a common measurement technique, however this process can be more susceptible to human error and is time consuming. Technology such as dynamic image analysis (DIA) can make particle size distribution analyses much easier. This approach can be seen in instruments ...

Occupational Safety And Health
Occupational safety and health (OSH) or occupational health and safety (OHS) is a multidisciplinary field concerned with the safety, health, and welfare of people at work (i.e., while performing duties required by one's occupation). OSH is related to the fields of occupational medicine and occupational hygiene and aligns with workplace health promotion initiatives. OSH also protects all the general public who may be affected by the occupational environment. According to the official estimates of the United Nations, the '' WHO/ ILO'' ''Joint Estimate of the Work-related Burden of Disease and Injury'', almost 2 million people die each year due to exposure to occupational risk factors. Globally, more than 2.78 million people die annually as a result of workplace-related accidents or diseases, corresponding to one death every fifteen seconds. There are an additional 374 million non-fatal work-related injuries annually. It is estimated that the economic burden of o ...

Prevention Through Design
Prevention through design (PtD), also called safety by design in Europe, is the concept of applying methods to minimize occupational hazards early in the design process, with an emphasis on optimizing employee health and safety throughout the life cycle of materials and processes. It is a concept and movement that encourages construction or product designers to "design out" health and safety risks during design development. The process also encourages the various stakeholders within a construction project to be collaborative and share the responsibilities of workers' safety evenly. The concept supports the view that along with quality, programme and cost; safety is determined during the design stage. It increases the cost-effectiveness of enhancements to occupational safety and health. Compared to traditional forms of hazard control, PtD possesses a proactive nature whereas other safety measures are reactive to incidences that occur within construction projects. This method fo ...

Steel-toe Boot
A steel-toe boot (also known as a safety boot, steel-capped boot, steel toecaps or safety shoe) is a durable boot or shoe that has a protective reinforcement in the toe which protects the foot from falling objects or compression. Safety shoes are effective in keeping the feet of industrial workers safe from sharp and heavy objects while working in factories. Safety footwear now comes in many styles, including Sneaker (footwear), sneakers, clogs, and dress shoes. Some are quite formal, for supervising engineers who must visit sites where protective footwear is mandatory. Some brands of steel-toe footwear have become fashionable within subcultures such as skinhead, Punk fashion, punk, and rivethead. While brands that were previously renowned within the fashion industry have also diversified into the safety footwear market, industrial brands like Caterpillar Inc.#Financial products and brand licensing, Caterpillar, Rock Fall and JCB have also issued licenses to produce safety footw ...

High-visibility Clothing
High-visibility clothing, sometimes shortened to hi vis or hi viz, is any clothing worn that is highly luminescent in its natural matt property or a color that is easily discernible from any background. It is most commonly worn on the torso and arm area of the body. Health and safety regulations often require the use of high visibility clothing as it is a form of personal protective equipment. Many colors of high visibility vests are available, with yellow and orange being the most common examples. Colors other than yellow or orange may not provide adequate luminescence for conformity to standards such as ISO 20471. As a form of personal protective equipment, high-visibility clothing is worn to increase a person's visibility and therefore prevent accidents caused by persons not being seen. As a result, it is often worn in occupations where hazardous situations are created by moving vehicles or low lighting conditions. These occupations include railway and road workers, airpo ...

Safety Glasses
Safety is the state of being protected from harm or other danger. Safety can also refer to the control of recognized hazards in order to achieve an acceptable level of risk. Meanings The word 'safety' entered the English language in the 14th century. It is derived from Latin , meaning uninjured, in good health, safe. There are two slightly different meanings of "safety". For example, " home safety" may indicate a building's ability to protect against external harm events (such as weather, home invasion, etc.), or may indicate that its internal installations (such as appliances, stairs, etc.) are safe (not dangerous or harmful) for its inhabitants. Discussions of safety often include mention of related terms. Security is such a term. With time the definitions between these two have often become interchanged, equated, and frequently appear juxtaposed in the same sentence. Readers are left to conclude whether they comprise a redundancy. This confuses the uniqueness that sh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hard Hat
A hard hat is a type of helmet predominantly used in hazardous environments such as industrial or construction sites to protect the Human head, head from injury due to falling objects (such as tools and debris), impact with other objects, and electric shock, as well as from rain. Suspension bands inside the helmet spread the helmet's weight and the force of any impact over the top of the head. A suspension also provides space of approximately 30 mm (1.2 inches) between the helmet's shell and the wearer's head, so that if an object strikes the shell, the impact is less likely to be transmitted directly to the skull. Some helmet shells have a mid-line reinforcement ridge to improve impact resistance. The Rock-climbing equipment#Helmet, rock climbing helmet fulfills a very similar role in a different context and has a very similar design. A bump cap is a lightweight hard hat using a simplified suspension or padding and a chin strap. Bump caps are used where there is a possibi ...

Tyvek
Tyvek () is a brand of synthetic flashspun high-density polyethylene fibers. The name ''Tyvek'' is a registered trademark of the American multinational chemical company DuPont, which discovered and commercialized Tyvek in the late 1950s and early 1960s. Tyvek's properties—such as being difficult to tear but easily cut, and waterproof against liquids while allowing water vapor to penetrate—have led to it being used in a variety of applications. Tyvek is often used as housewrap, a synthetic material used to protect buildings during construction, or as personal protective equipment (PPE). History Tyvek is a nonwoven product consisting of spun bond olefin fiber. It was first discovered in 1955 by a researcher for the DuPont textile company working in an experimental lab, who noticed a type of white fluff coming out of a pipe. That fluff was a form of polyethylene, which DuPont requested a patent for within a year of the discovery. After technologies improved during the next ...

Nomex
Nomex is a trademarked term for an inherently flame-resistant fabric with meta-aramid chemistry widely used for industrial applications and fire protection equipment. It was developed in the early 1960s by DuPont and first marketed in 1967. The fabric is often combined with Kevlar to increase its resistance for breakage or tear. Properties Nomex and related aramid polymers are related to nylon, but have aromatic backbones, and hence are more rigid and more durable. Nomex is an example of a '' meta'' variant of the aramids (Kevlar is a '' para'' aramid). Unlike Kevlar, Nomex strands cannot align during filament polymerization and have less strength: its ultimate tensile strength is . However, it has excellent thermal, chemical, and radiation resistance for a polymer material. It can withstand temperatures of up to . Production Nomex is produced by condensation reaction from the monomers ''m''-phenylenediamine and isophthaloyl chloride. It is sold in both fiber and s ...

Personal Protective Equipment
Personal protective equipment (PPE) is protective clothing, helmets, goggles, or other garments or equipment designed to protect the wearer's body from injury or infection. The hazards addressed by protective equipment include physical, electrical, heat, chemical, biohazards, and airborne particulate matter. Protective equipment may be worn for job-related occupational safety and health purposes, as well as for sports and other recreational activities. ''Protective clothing'' is applied to traditional categories of clothing, and ''protective gear'' applies to items such as pads, guards, shields, or masks, and others. PPE suits can be similar in appearance to a cleanroom suit. The purpose of personal protective equipment is to reduce employee exposure to hazards when engineering controls and administrative controls are not feasible or effective to reduce these risks to acceptable levels. PPE is needed when there are hazards present. PPE has the serious limitation that it d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
