Combustible Dust Safety
This type of dust, when dispersed in air and ignited, can cause an explosion.
What is combustible dust?
This type of protective gear is essential for workers when handling molten metal to prevent burns.
What is heat-resistant PPE?
This device, found on every floor of a home, can detect smoke and prevent fire-related fatalities.
What is a smoke alarm?
(Installing smoke alarms reduces the risk of dying in a home fire by half.)
This policy requires a thorough assessment and approval process before making any significant modifications to equipment, processes, or personnel.
What is the Management of Change policy?
This essential process safety technique involves systematically identifying and assessing potential hazards in new or modified processes.
What is a Hazard Study?
One method to prevent dust explosions is through this practice to reduce dust accumulation.
What is proper housekeeping?
This practice involves keeping hydrated and taking breaks to avoid this common risk when working in high-temperature environments.
What is heat stress?
This colorless, odorless gas is known as the "silent killer" because it can cause poisoning without warning, especially from malfunctioning fuel-burning appliances.
What is carbon monoxide?
(Carbon monoxide poisoning results in about 50,000 emergency department visits each year in the U.S.)
This policy requires that all work inside these spaces, where there is a risk of death or serious injury, must only be done if there is no practical alternative.
What is the Confined Space Entry policy?
According to JM's process safety standards, this type of assessment is mandatory for evaluating the risks associated with high-severity events like fires or toxic releases.
What is a Maximum Credible Event (MCE) assessment?
DHA, a crucial process in dust safety, stands for this.
What is Dust Hazard Analysis?
This type of extinguisher is used specifically for fires involving combustible metals, such as magnesium and aluminum.
What is a Class D fire extinguisher?
This safety feature, required by law in newer homes, can prevent electrical shocks by automatically shutting off power when it detects dangerous currents in outlets near water sources.
What is a Ground Fault Circuit Interrupter (GFCI)?
(GFCIs are critical in preventing electrical shocks in areas like bathrooms, kitchens, and outdoor outlets.)
This system must be used to control hazardous work, such as hot work or working on live electrical systems, ensuring all safety measures are in place before work begins.
What is the Permit to Work system?
This risk analysis method, often used in detailed Hazard Studies, assesses the reliability of protective systems by evaluating multiple layers of safety.
What is Layer of Protection Analysis (LOPA)?
Along with fuel, an ignition source, and oxygen, these two elements are part of the dust explosion pentagon.
What are dispersion and confinement?
This method is used to remove impurities from molten metal before it is poured into molds.
What is slag skimming?
This item, when not properly hydrated and placed too close to heat sources like candles or fireplaces, is responsible for an estimated 25% of all home fires during the holiday season.
What is a natural or live Christmas tree?
(Dried-out real Christmas trees, especially near heat sources, are a significant cause of holiday fires. Regular watering can help prevent this.)
This procedure involves securing equipment to prevent the release of hazardous energy, ensuring the safety of workers during maintenance or repair activities.
What is lockout/tagout (Process and Mechanical Isolation)?
For complex new projects, this specific type of Hazard Study, often referred to by its acronym, is conducted to evaluate the operational consequences of failures.
What is a Hazard and Operability Study (HAZOP)?
According to safety standards, the maximum allowable dust layer thickness before cleaning is typically set at this measurement to prevent fire and explosion hazards.
What is 1/32 of an inch?
Before entering a confined space in a foundry, you must ensure the atmosphere is tested for this invisible, odorless gas produced during metal casting.
What is carbon monoxide?
Before embarking on long winter road trips during the holidays, drivers should not only check their tires and windshield wipers but also ensure that this often-overlooked item that can be affected by the snow is appropriate for the environment.
What is windshield washer fluid with antifreeze properties?
(Using washer fluid rated for freezing temperatures can prevent dangerous ice buildup on windshields during winter travel.)
This element of the Working at Height policy requires that, if the risk of a fall cannot be eliminated, these measures must be used to minimize the distance and consequences of a fall.
What are fall arrest or restraint systems?
This process safety element ensures that any changes to existing processes are evaluated against their potential impact on safety, often involving the re-assessment of Maximum Credible Events.
What is Management of Change (MoC)?
