The windshield is a large piece of transparent glass in the front of vehicles that protects the driver and passengers from wind, dust, insects, rocks and other debris. It also provides a panoramic view for the driver. The windshield is made of laminated safety glass that is bonded to the vehicle frame with special adhesives.
The first windshields were made of ordinary window glass, which shattered when hit with something. This was dangerous because sharp shards flew toward the driver and passengers, injuring them. The problem was solved with the introduction of laminated glass, which is far more shatter-resistant. Today’s windshields are made of a strong, transparent material called polycarbonate. They are reinforced with a resin that binds the layers of glass together.
If the glass gets damaged, it can be repaired by injecting clear adhesive resin into the crack or chip to replace air that was trapped there. The process takes less than an hour and restores the strength of the glass and 90-95% of its clarity. The windshield is a critical component of the structural integrity of the cabin in a front-end crash or rollover, providing up to 45% of the force absorbed by the passenger compartment.
A windshield has several other functions, including reducing aerodynamic drag and helping to direct airflow over the engine and other mechanical parts. It also helps to prevent fogging, which reduces visibility and can create a distraction for the driver. It also acts as a barrier to rain, snow and other weather conditions.
Windshield surveys and walking surveys are systematic observations that allow nurses to assess a community and determine whether a particular health-related issue is present. Nurses can use these methods to evaluate a variety of things, including the condition of roads and bridges; public buildings such as hospitals and schools; and water and air quality.
When preparing for a windshield or walking survey, it’s important to follow best practices. Review the directions and grading rubric carefully and complete all sections of the form. Use a professional writing style and check for spelling and grammar errors prior to submission. Windshield and walking surveys are an excellent way for nurses to become involved in their communities and advocate for healthier environmental practices.
For example, windshield surveys can alert residents to pollution and toxins in the environment that could affect their health. The results of these observations can inspire educational programs to promote environmental health and safety, as well as regulatory changes that may reduce or mitigate environmental hazards. Nurses can also use windshield and walking surveys to assess the needs of their local communities by collecting information that will help them develop a plan to improve conditions.
