The goal, obviously, is to choose a new chemical that is less hazardous than the original. They directly address the hazard and do not depend on employees’ actions to be effective. Scheduled maintenance - Thursday, July 12 at 5:00 PM EDT. Working at Height Hazards and Control Measures Fundamental elements of fall prevention . Substitute dangerous chemicals, equipment or work methods with safer and less hazardous ones to eliminatethe hazard altogether. A legal limit or guideline (such as an exposure limit) should never be viewed as a line between "safe" and "unsafe". Sometimes referred to as a pyramid, the hierarchy of hazard controls has four levels. Working at height remains one of the biggest causes of occupational fatalities and major injuries. Contact us to let us know. Substitution may also include using a machine that requires less energy, or lifting items with less weight. Using a work-rest schedule that limits the length of time a worker is exposure to a hazard. Administrative controls address how the work is structured, such as work pace and breaks. Example: Exhaust ventilation can be used to remove a harmful substance such as carbon dioxide (dry ice) from the air. Easy-to-read, question-and-answer fact sheets covering a wide range of workplace health and safety topics, from hazards to diseases to ergonomics to workplace promotion. Scheduling maintenance and other high exposure operations for times when few workers are present (such as evenings, weekends). Remember, however, that you need to make sure the substitute chemical or substance is not causing any harmful effects, and to control and monitor exposures to make sure that the replacement chemical or substance is below occupational exposure limits. Developing and implementing safe work procedures or standard operating procedures. The best way to protect workers is to remove or eliminate the hazard from the workplace using the following hazard control methods: Substitution. Care must be taken when the enclosure is opened for maintenance as exposure could occur if adequate precautions are not taken. Cases commonly involve over-reaching, over-balancing or the failure of a fragile surface. It is the preferred way to control a hazard and should be used whenever possible. In addition, both "normal" and any potential or unusual situations must be studied. Key point: A hazard is anything that could hurt you or someone else. Preparing and training for emergency response for incidents such as spills, fire or employee injury. Selecting an appropriate control is not always easy.

Restricting the task to only those competent or qualified to perform the work. Some tools include physical inspection, testing, exposure assessment, observations, injury and illness tracking, accident/incident investigations reports, employee feedback/input, occupational health assessment and other methods. These control measures have many limitations because the hazard itself is not actually removed or reduced. Common isolation techniques are to create a contaminant-free or noise-free booth either around the equipment or around the employee workstations. An effective plan will address serious hazards first. ... Equipment and method… These methods are often called engineering controls. The above hazard control methods can be applied in combination in order to provide the most effective hazard control. You may also be interested in the following related products and services from CCOHS: Although every effort is made to ensure the accuracy, currency and completeness of the information, CCOHS does not guarantee, warrant, represent For example, in the case of a noise hazard, temporary measures might require workers to use hearing protection. Some sources may use a variation of this hierarchy. Use wet methods rather than dry when drilling or grinding. For example, a dry, dusty powder may be a significant inhalation hazard but if this material can be purchased and used as pellets or crystals, there may be less dust in the air and therefore less exposure. Use automation - the less workers have to handle or use the materials, the less potential there is for exposure. Some elements of safe work practices include: Employee education and training on how to conduct their work safely helps to minimize the risk of exposure and is a critical element of any complete workplace health and safety program. Traditionally, a hierarchy of controls has been used as a means of determining how to implement feasible and effective control solutions.One representation of this hierarchy is as follows:The idea behind this hierarchy is that the control methods at the top of graphic are potentially more effective and protective than those at the bottom. No matter which type of PPE is used, it is essential to have a complete PPE program in place. At the source (where the hazard "comes from"). If it is not reasonably practical to eliminate the hazards … The most preferred method of controlling risk is to eliminate the hazard altogether. Enclosure and/or isolation of emission source. Contact our Safety InfoLine • Is the establishment following all procedures (i.e., prerequisite or other programs) identified in the hazard … Use an appropriate vacuum or "wet method" instead of dry sweeping (e.g. Access to this website will be unavailable during this time. PPE, work practice controls, and administrative controls are considered the least effective hazard controls. At the end of the day, the smartest and easiest way to reduce incidents in the workplace is to make people more conscious and aware of what they are doing. These controls, however, are always going to be necessary in the meatpacking, poultry and food processing industries. Use steam cleaning instead of solvent degreasing (but be sure to evaluate the potential high temperature hazard being introduced such as heat stress). There are many other ways to assess risk and hazards, including methods designed for specific industries or applications. Conduct incident investigations. Washing hands after handling material and before eating, drinking or smoking. Examples of workplace hazards … Warnings. During the ev… Expert guidance should be sought. The fan must overcome all the losses due to friction, hood entry, and fittings in the system while producing the intended flow rate. It removes the contaminant at the source so it cannot disperse into the work space and it generally uses lower exhaust rates than general ventilation (general ventilation usually exchanges air in the entire room). Spill control kits can be used to neutralise or absorb the spilled chemical. Most Effective Hazard Controls The best way to protect workers is to remove or eliminate the hazard from the workplace using the following hazard control methods: Substitution. Please see the OSH Answers document on emergency planning for more information. We expect this update to take about an hour. Other examples include "glove boxes" (where a chemical is in a ventilated and enclosed space and the employee works with the material by using gloves that are built in), abrasive blasting cabinets, or remote control devices. A local exhaust ventilation system consists of these basic parts: The design of a ventilation system is very important and must match the particular process and chemical or contaminant in use. NIOSH recommends that employers examine any job or activity that puts employees at risk of injury. See the OSH Answers document Substitution of Chemicals: Considerations for Selection for more information. Systems that increase awareness are methods that help the worker to detect if a hazard is present. Before deciding to replace a chemical/substance with another, consider all the implications and potential risks of the new material. Is the risk posed by the original hazard contained? When necessary, methods of administrative control include: Work practices are also a form of administrative controls. It often involves doing a risk assessment to evaluate and prioritize the hazards and risks. In most cases, elimination is not feasible and when possible, substitution is the best approach to hazard mitigation. Lukman Nulhakiem is a production engineer who works for a hydrogen peroxide plant … Personal Protective Equipment (PPE). A hazard control plan describes how the selected controls will be implemented. Are new hazards appropriately controlled? Decrease the temperature of a process so that less vapour is released. Control of hazards requires the use, appropriate to the situation, of four basic approaches: engineering controls, administrative arrangements, safe work practices, preventive maintenance and the use of … They are particularly effective if the contaminant(s) can accumulate on the skin, clothing or hair. Engineering Controls. Fol… Employers should begin at the top of the pyramid and work their way down when trying to reduce hazards.The top level of the hierarchy is elimination, which is when a hazard is completely taken out of the workplace. Good housekeeping is essential to prevent the accumulation of hazardous or toxic materials (e.g., build-up of dust or contaminant on ledges, or beams), or hazardous conditions (e.g., poor stockpiling). It is a widely accepted system promoted by numerous safety organizations. Examples of personal hygiene practices include: Personal protective equipment (PPE) includes items such as respirators, protective clothing such as gloves, face shields, eye protection, and footwear that serve to provide a barrier between the wearer and the chemical or material. Local exhaust ventilation is very adaptable to almost all chemicals and operations. The hazard controls in the hierarchy are, in order of decreasing effectiveness: Elimination Substitution Engineering controls Administrative It must also provide them with information on how to protect themselves and co-workers. Engineering controls include these methods: 1. A hazard control program consists of all steps necessary to protect workers from exposure to a substance or system, the training and the procedures required to monitor worker exposure and their health to hazards such as chemicals, materials or substance, or other types of hazards such as noise and vibration. For more information about PPE programs, please see the following document Designing an Effective PPE Program. seeks to protect workers by ranking the ways in which hazards can be controlled A Job Hazard Analysis (JHA) is an analysis of the hazards and risk associated which focus on identifying and controlling hazards. PPE is the least effective way to protect workers from workplace hazards because if the equipment fails, workers are exposed to the hazard. When substituting, be very careful that one hazard is not being traded for another. A written workplace hazard control program should outline which methods are being used to control the exposure and how these controls will be monitored for effectiveness. Be sure to answer the following questions: Adapted from the Occupational Health and Safety Committee Manual prepared by the Saskatchewan Government.

Enclosed equipment, for example, is tightly sealed and it is typically only opened for cleaning or maintenance. For example, the CSA Standard 1002-12: Occupational health and safety â Hazard identification and elimination and risk assessment and control includes a level called "systems that increase awareness of potential hazards". Absorbent pillows can be laid around the spill to prevent the chemical from spreading out. It is important to know if all workplace hazards are identified, assessed and appropriately controlled. A strong safety culture is at the heart of any safety-conscious … Air cleaning devices may also be present that can remove contaminants such as dust (particulates), gases and vapours from the air stream before it is discharged or exhausted into the environment (outside air), depending on the material(s) being used in the hood. Have workers been adequately informed about the situation? Using job-rotation schedules that limit the amount of time an individual worker is exposed to a substance. Implementing permanent controls when reasonably practicable. Check out our Whatâs New listing to see what has been added or revised. • Can the establishment support that the hazard is not reasonably likely to occur (NRLTO)? Example: Metal mesh gloves are often the only way to protect workers from knife cuts, but the hazard of exposure to sharp knives is still present. Control at the source and control along the path are sometimes also known as engineering controls (see below for more details). How can we make our services more useful for you? Another type of substitution includes using the same chemical but to use it in a different form. Interim controls may be necessary, but the overall goal is to ensure effective long-term control of hazards. However, regardless of the number of levels included, the hierarchy should be considered in the order presented (it is always best to try to eliminate the hazard first, etc). Redesign the process. The best way to protect employees from hazards is to remove hazards from the workplace altogether, or at least keep them away from employees. Work practice controls change the way workers do their jobs to reduce exposure to hazards. Conducting pre-start discussions allows everyone to talk about what might go right or wrong, what other people have encountered when working on this before (together people have seen and identified more hazards) and to bring awareness to the job being done today. Ductwork (exhaust stack and/or recirculation duct) that carries the contaminated air to the air cleaning device, if present or to the fan (away from the source). Spot the hazard. It is a very effective control measure but only if it is designed, tested, and maintained properly. Isolation places the hazardous process "geographically" away from the majority of the workers. The elimination stage of the hierarchy of controls is by far the most effective, because it removes the risk of incident altogether. The most preferred method of controlling risk is to eliminate the hazard altogether. Substitution occurs when a new chemical or substance that is less hazardous is used instead of another chemical. Various illustrations are used to depict this system, most commonly a triangle. Add a badge to your website or intranet so your workers can quickly find answers to their health and safety questions. Reduce vapour concentrations by … These methods will reduce the amount of paint that is released into the air. Ventilation is a method of control that strategically "adds" and "removes" air in the work environment.
