CSA Safety Clothing Striping (Canada)
Under CSA Z96-15, the Canadian standard for high-visibility safety apparel, the goal is to provide clear visibility for workers, particularly in low-light conditions. The standard focuses on the use of fluorescent colours (like orange or yellow) combined with reflective striping to enhance visibility.
Key Details for CSA Striping:
-
Classifications of Safety Clothing: CSA safety clothing is divided into three classes based on the level of visibility needed, and these classifications determine how much reflective striping is required:
-
Class 1:
- For workers who face low-risk situations (like working in parking lots or areas with low traffic).
- Amount of striping: Requires reflective striping on at least 1.6 meters of the garment’s circumference. Reflective strips must cover the torso and sleeves.
- The total visible reflective area is typically smaller in Class 1 compared to Class 2 or Class 3.
-
Class 2:
- For workers in environments with moderate risk (like workers on roadways or in situations with higher traffic flow).
- Amount of striping: Requires more reflective material than Class 1, with reflective strips covering at least 3.1 meters of the garment’s circumference, usually across the torso and sleeves.
- Reflective strips are applied in a way that ensures 360-degree visibility from the front, back, and sides.
-
Class 3:
- For high-risk work environments (like highway construction, where workers may be exposed to fast-moving traffic or other hazards).
- Amount of striping: Requires the most reflective striping. Reflective material should cover at least 5.1 meters of the garment’s circumference. This includes the torso, arms, and legs.
- Workers are often required to wear full-body coverage that ensures visibility in all directions. Reflective strips are placed not only on the torso and sleeves, but also around the legs for complete 360-degree visibility.
-
-
Material and Placement:
- The striping must be reflective (like silver or white reflective tape) and made from retroreflective material that will return light to its source.
- The material should be placed at strategic locations to maximize visibility: around the waist, across the chest, shoulders, and sleeves (depending on the class).
- The width of the reflective stripes is typically around 5 cm for optimal visibility.
OSHA Safety Clothing Striping (U.S.)
The OSHA standards for high-visibility clothing are laid out under ANSI/ISEA 107-2020, a U.S. standard based on the Federal OSHA guidelines. These standards are focused on improving worker visibility in high-risk environments, particularly in construction, roadwork, and highway maintenance.
Key Details for OSHA Striping:
-
Classifications of Safety Clothing: OSHA uses three classes of high-visibility clothing, with each class specifying a minimum amount of reflective striping based on the risk level of the work environment:
-
Class 1:
- For workers in areas with minimal traffic or low-risk exposure, such as parking lots or warehouses.
- Amount of striping: Requires reflective material to cover at least 217 square inches (about 1.5 meters of reflective striping) of the garment. Reflective material should be applied around the torso.
- Reflective stripes are typically placed around the waist and possibly the shoulders but without the extensive coverage required by higher classes.
-
Class 2:
- For workers who are exposed to moderate-risk situations, such as roadway work or loading docks.
- Amount of striping: Requires at least 310 square inches (around 2.1 meters of reflective striping). Reflective material should be applied across the torso, arms, and shoulders for 360-degree visibility.
- Workers may also need leg bands or additional reflective material on the sleeves.
-
Class 3:
- For workers exposed to high-risk environments where visibility is critical, such as construction zones on highways, airports, or emergency responders.
- Amount of striping: Requires the most reflective material, covering at least 775 square inches (about 5.3 meters of reflective striping). This ensures maximum visibility in all directions.
- Reflective material is placed around the torso, arms, and legs, ensuring complete 360-degree visibility.
- Full-body coverage is often required, including reflective bands around legs (in addition to torso and sleeves).
-
-
Material and Placement:
- Like CSA, OSHA requires retroreflective material (such as silver or white) and fluorescent colours (like fluorescent yellow-green or orange-red) to increase daytime visibility.
- The reflective stripes must be placed in specific locations on the garment to maximize safety:
- Class 1: Waist area only.
- Class 2: Waist, chest, and arms.
- Class 3: Full torso, sleeves, and legs (complete visibility).
Comparison of Striping Requirements:
Aspect | CSA (Canada) | OSHA (U.S.) |
---|---|---|
Class 1 | Minimal striping, reflective material on torso and sleeves. Around 1.6 meters of striping. | Minimal striping, reflective material on torso. 217 square inches (~1.5 meters of striping). |
Class 2 | Reflective material around torso, sleeves. Around 3.1 meters of striping. | Reflective material on torso, arms, and shoulders. 310 square inches (~2.1 meters). |
Class 3 | Full coverage, including torso, sleeves, and legs. Around 5.1 meters of striping. | Full coverage, including torso, arms, and legs. 775 square inches (~5.3 meters). |
Reflective Material | Retroreflective strips required for all classes. | Retroreflective strips required for all classes. |
Placement | Torso, arms, and legs (Class 3). | Torso, arms, and legs (Class 3). |
Summary:
- CSA safety clothing has three classes (1, 2, 3), with reflective striping increasing as the risk of the environment rises. Class 3 requires the most striping, with reflective material covering the torso, arms, and legs for full 360-degree visibility.
- OSHA uses similar Class 1, 2, and 3 categories, but the exact amount of striping and the placement may differ slightly. Class 3 requires the most reflective material—over 5 meters of striping, and in high-risk environments, it covers the torso, arms, and legs.
In both cases, the goal is to ensure that workers are visible in low-light and hazardous conditions to reduce accidents and injuries.
