Silica in Construction
Silica exposure is a threat for approximately 2.3 million US workers and is especially dangerous for more than 100,000 workers who make up the nation's stonecutters, foundry workers, sandblasters, and rock drillers. Crystalline silica is classified as a human lung carcinogen and is known to cause respiratory diseases, including an especially damaging one – silicosis. Effective measures are available to protect workers from exposure and to reduce and prevent its potentially devastating health effects. It's important that employees recognize the potential hazards of silica exposure so they can protect themselves. This course covers hazard recognition, potential health threats, exposure prevention, and control measures and focuses on construction-specific requirements as promulgated in 29 CFR 1926.1153. This course was developed with subject matter support provided by EnSafe Inc., a global professional services company focusing on engineering, environment, health and safety, and information technology.

Sprains and Strains
Each year, thousands of workers are injured in the workplace, costing employers billions of dollars in hidden costs. The most common of these injuries are sprains and strains. Most workplace injuries are caused by manual tasks, such as lifting or carrying loads, working in fixed positions, repetitive tasks, or using heavy, vibrating tools. Manual tasks, if not performed properly, are a leading cause of serious worker injuries such as sprains and strains, as well as permanent spinal damage, and often can debilitate workers who may need to take leave from work for extended periods. Workplace injuries can be costly to both employees and employers. In addition to being injured, employees may lose time from work, which could result in loss of or less income. And employers may experience lower productivity due to the need to replace the injured worker and train replacements. The course is designed to help you better understand sprains and strains so you will be more aware of what you are doing and how you are doing it, in an effort to prevent this type of injury from happening to you. The course was developed and reviewed with subject matter support provided by certified subject matter experts and industry professionals.
