Although the three classes of oxidizer may have different physical states, they share the characteristics of oxidizers and they all pose fire hazards if appropriate handling and storage needs are not followed.

In addition to chronic toxicity hazards, remember that a product may have additional hazardous properties such as being acutely toxic (e.g., can have immediate toxic effects) or it may have other hazardous properties such as being corrosive or flammable.

Deer/Cattle Crossing. These signs warn of a deer/cattle crossing ahead. Stay alert for deer/cattle suddenly entering the road.

Flammable hazards are products that can ignite easily and burn rapidly. For a fire to occur, three elements must be together at the same time and in the right proportions: fuel, oxygen, and heat (e.g., an ignition source such as a spark). It is very important for fire prevention and when working safely with flammable products to make sure that these three elements are not present together in the right amounts at any time.

Because of the high risk of significant personal injury and extensive property damage for incidents involving these products, proper training and appreciation of the hazards is essential.

Liquefied gases are gases which can become liquids at normal temperatures when they are inside cylinders under pressure. Refrigerated liquefied gases are those gases that are made partially liquid because of its low temperature. Initially the cylinder is almost full of liquid, and gas fills the space above the liquid. As gas is removed from the cylinder, enough liquid evaporates to replace it, keeping the pressure in the cylinder constant. Examples: anhydrous ammonia, chlorine, propane, nitrous oxide and carbon dioxide

Consumer products are chemical products sold to Canadians for general household use that have certain hazards (such as toxic, corrosive, flammable). Consumer products use different symbols than WHMIS.

For example: A highly toxic chemical can have a low health hazard if it is used with proper precautions and care. On the other hand, it is possible that a chemical of low toxicity may present a high health hazard if it is used inappropriately. These differences make proper handling and control measures very important.

Dangerousdip sign meaning

Biohazardous infectious materials are usually found in a hospital, health care facility, laboratories, veterinary practices and research facilities. Workers in these places do not usually know which tissues or fluids contain dangerous organisms. For this reason, the workers assume that every sample is hazardous and proper protection is used all the time. Examples of biohazardous infectious materials include the AIDS/HIV virus, Hepatitis B and salmonella.

If the product only has this pictogram, the main concern is its toxicity for aquatic life. If the material has other pictograms, it is also hazardous to humans in the workplace (e.g., physical or health hazards).

* Note that the most hazardous categories (Types A, B) within these classes will use the explosion pictogram alone or with the flammable pictogram

Note: The exclamation mark may also be used to indicate products that contribute to the depletion of the ozone layer. Recall that classification and labelling of the environmental hazard group is not mandatory in Canada. However, suppliers may indicate these hazards on labels and SDSs if they choose to.

Acetylene is the only commonly used dissolved gas. Acetylene is chemically very unstable and at atmospheric pressure, acetylene gas can explode. However, acetylene is routinely stored and used safely in cylinders because the acetylene cylinders are packed with an inert, porous filler. The filler is saturated with acetone or other suitable solvent. When acetylene gas is added to the cylinder, the gas dissolves in the acetone to create a stable solution.

Corrosive products such as strong acids and strong bases can attack (corrode) metal or our skin/eyes. Common acids include hydrochloric acid, nitric acid and sulfuric acid. Common bases are sodium hydroxide (caustic soda) and ammonia. Check the labels and read the SDS (Section 10: Stability and reactivity) for additional information.

Low Ground Clearance Railroad Crossing. This sign indicates that the railroad crossing is slightly raised compared to the road. Low ground clearance vehicles may get stuck while trying to cross.

r rsign meaning

Acute toxicity refers to effects occurring following skin contact or ingestion exposure to a single dose, or multiple doses given within 24 hours, or an inhalation exposure of 4 hours.

Most pictograms have a distinctive red "square set on one of its points" border. Inside this border is a symbol that represents the potential hazard (e.g., fire, health hazard, corrosive, etc.).

Chronic health effects occur from exposure to a product over a period of time, often measured in days, months or years. Long-term health effects such as carcinogenicity (cancer causing) or respiratory sensitization are included under this pictogram. In addition, this pictogram is used for products which can cause targeted health impacts on a specific organ system (such as the kidneys, nerves or liver) that develop after a single exposure or after repeated exposure.

Trucksign meaning

ALWAYS check the product's SDS and the label on the containers to ensure that you know what is being used and the full range of potential hazards associated with a product.

Turn (Left/Right). This sign indicates a sharp turn in the direction of the arrow ahead. Slow down and proceed with caution.

This pictogram indicates that the damage caused by exposure to the corrosive material is very significant and likely irreversible. Lower hazard categories (e.g., skin or eye damage that will heal/be reversible) for the two health classes will use the exclamation mark hazard pictogram or no pictogram in some cases.

This pictogram is also used to indicate two health hazard classes for products that can cause destructive, irreversible damage to the skin and eyes. The two hazard classes are:

Together, the symbol and the border are referred to as a pictogram. Pictograms are assigned to specific hazard classes or categories.

Right Lane Ends. This warning sign indicates that the right lane ends ahead. Vehicles traveling in the right lane must merge left.

Hazard Marker. These signs are usually placed on or near objects close to the road. The sign varies depending on which side of the road the object is located. In this case, you should drive on the right side of the sign.

The basic components for a fire are a source of fuel (such as combustibles), a source of oxygen, and a spark or source of ignition.

Reverse Curve (First Curve to the Left). This warning sign indicates that there is a reverse curve ahead. In this case, the road curves to the left and then to the right.

In addition to meeting the criteria for this hazard pictogram, remember that a product may have additional hazardous properties such as being acutely toxic (e.g., can have immediate toxic effects) or it may have other hazardous properties such as being corrosive or flammable.

Thousands of products are available which contain gases and mixtures of gases that are stored under pressure in cylinders.

Two-Way Traffic. This sign warns of two-way traffic ahead. It’s often shown when you are leaving a separated one-way road and entering a two-way road.

Yield Ahead. This sign warns that you are approaching a Yield sign. Slow down to a speed at which you can yield if necessary.

Acute toxicity could result from exposure to the product itself, or to a product that, upon contact with water, releases a gaseous substance that is able to cause acute toxicity.

Consumer product symbols are framed by one of two shapes, which signify whether it is the contents of the container or the container itself that is dangerous.

Non-liquefied gases are also known as compressed, pressurized or permanent gases. These gases do not become liquid when they are compressed at normal temperatures, even at very high pressures. Examples are oxygen, and nitrogen.

Road Slippery When Wet. This warning sign indicates that the road ahead is slippery when wet. Adapt your speed to the conditions when you come upon this sign.

This pictogram is also used by two health hazard classes for products that can cause destructive, irreversible damage to the skin and/or eyes.

Speed Limit Ahead. This warning sign indicates that you are approaching a reduced speed zone. In this case, the speed limit ahead is 45 mph.

Why? Because warning signs are used to alert drivers to an unexpected or dangerous road condition or traffic situation.  This means it can be dangerous to misunderstand a warning sign. Traffic warning signs are usually yellow or orange with black symbols on a diamond-shaped or rectangular sign.

WHMIS groups products with similar properties or hazards into classes. The Hazardous Products Regulations specifies the criteria used to place products within each classification. WHMIS classifications are made by the manufacturer or supplier for products to be used in Canada.

Low Clearance. This sign indicates you are approaching an overpass. There is 12 feet 6 inches of clearance from the road to the overpass.

Curve with Advisory Speed Limit. This sign indicates that the road will curve to the right. The advisory speed limit for this curve is 35 mph under ideal conditions.

Turn With Advisory Speed Limit. This sign indicates a sharp right turn ahead. The advisory speed limit for this curve is 25 mph under ideal conditions.

Main Road Curves to the Right Ahead. This sign indicates that the main road curves right with a side road entering from the left side in the curve.

Double-Side Roads. This sign indicates there will be double-side roads on the left side. Be prepared for traffic entering the road from the side roads.

ALWAYS check the product's SDS and label on the containers to ensure that you know what is being used and the full range of potential hazards associated with a product.

Merge (Right). This sign indicates that traffic from the right will merge ahead. Be prepared for vehicles entering your lane!

Ten pictograms are used by WHMIS 2015. Pictograms are graphic images that immediately show the user of a hazardous product what type of hazard is present. With a quick glance, you can see, for example, that the product is flammable, or if it might be a health hazard.

WHMIS (Workplace Hazardous Materials Information System) helps identify the hazards of products like chemical and infectious agents.

Side Road at Acute Angle. This warning sign indicates there’s an upcoming side road at an acute angle. Be prepared for traffic entering the road from the side road.

Dip. This sign warns that the road goes down abruptly (dips) in the road ahead. Slow down to prevent damaging your vehicle.

Merge (Left). This road sign indicates that traffic from the left will merge ahead. Be prepared for vehicles entering your lane!

Divided Highway. This warning sign indicates a divided highway. The traffic lanes ahead are divided by a median/divider.

Narrow Bridge Ahead. This sign warns of a narrow bridge ahead. The bridge is narrower than the road you are driving on, so you may need to yield to wide vehicles on the bridge.

Hairpin Curve. This sign indicates a hairpin curve ahead. A hairpin curve is a very sharp curve that often completely reverses your direction of travel.

Chronic toxicity is different than acute toxicity. Acute toxicity refers to immediate health effects as a result of exposure to a toxic product. Chronic toxic effects tend to develop over time, often as a result of long-term exposure to a particular product. As an example, smoking a single cigarette is unlikely to cause a lasting toxic effect but smoking many cigarettes over time is linked with numerous adverse health effects. Chronic toxicity can also refer to a persistent adverse health effect that occurred as a result of a short-term exposure to a toxic product. For some chronic toxicity hazards, there is no known safe amount to which a person can be exposed.

Materials in this class should only be used or handled by individuals who are thoroughly trained and aware of the hazards and how to control them. This level of training is beyond the scope of this course.

The health impacts covered by this pictogram may not be obvious to the worker right away, but the effects are generally reversible and of relatively short duration with proper medical treatment (and when further exposure is prevented). Always read the SDS and compare it with the label for the product. Understand how to use the product safely. Ask questions if you are unsure.

One Direction Arrow. This sign indicates that you are only allowed to travel in the indicated direction. In this case, to the left.

This pictogram is used by a number of hazard classes in the health hazard group. If you see this pictogram on a product, it indicates that regular exposure could result in serious health issues. The health impacts will not be obvious right away. Always read the SDS and compare it with the label for the product. Understand how to use the product safely. Ask questions if you are not sure.

Road signs meanings

Fire and explosion are the main concerns, but other issues may be present. If a product is classified as flammable, the supervisor and workers must understand specifics of what the hazards are and how to use it safely.

The hazard categories address explosives in terms of unstable explosives; mass explosion hazard; severe projection hazard; fire, blast or projection hazard and may explode in fire.

There are many categories within the acute toxicity class. There are categories used to describe the different ways the product can enter the body ( e.g., oral (ingested/eaten), dermal (skin), or inhalation (breathed in).

Toxicity of a chemical does not change, but the risk of exposure from using it can be controlled and minimized through proper handling and storage practices.

Products with this pictogram should only be used by individuals who are thoroughly trained and aware of the hazards and how to control them. This level of training is beyond the scope of this Kit.

Side Road at Perpendicular Angle. This sign indicates there’s an upcoming side road at a T-intersection. Be prepared for traffic entering the road from the side road.

Any time you drive, you are likely to spot anywhere from a few to over a dozen different warning signs. Despite learning the most common warning signs for driving, every new driver will at some point come upon a traffic warning sign they simply have no clue about. It’s worth taking a moment to read up on the signs you are unsure about.

The pictogram for oxidizing products is an "o" with flames on top of it. The "o" is for oxygen and the flames show that oxidizers are significant fire hazard if they are not handled properly. There are three types of oxidizing product: oxidizing gases, oxidizing liquids and oxidizing solids.

Two Directional Arrow. This sign indicates that you are not allowed to go straight ahead. You must turn either left or right.

Pavement Ends Ahead. This sign indicates that the pavement ends ahead. The road will likely turn into a gravel or dirt road.

Tsign meaning

Y-Roads. This road sign indicates that the road is about to split into two different directions. Be alert for other vehicles changing lanes.

If you prefer video, we’ve created one with driving instructor Jacqueline. She will drive along a route filled with important road signs and explain what to look for and what they mean.

Recall that classification and labelling of this hazard group is not mandatory in Canada. However, suppliers may indicate these hazards on labels and SDSs if they choose to.

The primary hazard of oxidizing products is fire and explosion. In addition to property damage, if an oxidizer product contaminates the skin or clothing, there is a high risk of very significant personal injury in the event of a fire.

Divided Highway Ends. This sign indicates the end of a divided highway. The traffic lanes ahead will no longer be divided by a median/divider.

With oxidizers, these products readily give off oxygen or other oxidizing substances (such as bromine, chlorine, or fluorine) and this is a significant fire/explosion risk. Oxidizers do not burn by themselves but oxidizers can:

Railroad Crossing Ahead. This sign is posted before most railroad crossings. Slow down to a speed at which you can safely stop, and be alert for a train.

These materials are organisms or the toxins they produce that can cause diseases in people or animals. Included in this class are bacteria, viruses, fungi and parasites. As these organisms can live in body tissues and fluids, they should be treated as toxic. Urine and feces should be treated as toxic only if they are visibly contaminated with blood.

For example, vapours from a flammable liquid can mix with air and be exposed to the right amount of heat to ignite and burn. In the workplace, controlling the fuel (e.g., flammable products), keeping quantities low, and eliminating sources of ignition are the main ways that allow flammable products to be handled safely.

Aquatic hazards may include "acute hazards to the aquatic environment" which evaluates short-term toxic impacts on various aquatic life forms (such as fish, crustaceans, algae and aquatic plants). It also includes "long-term hazards to the aquatic environment" which evaluates long-term (chronic) negative impacts on aquatic life forms such as bioaccumulation (buildup of material in organism) and degradation (persistence, or how long it will remain in the environment). Examples of long-term impacts for the aquatic environment could include reduced spawning, genetic problems in offspring and behavioural changes.
