Structural failure can often produce catastrophic results. In many cases, the damage seen after the accident is not indicative of the cause of the initial failure. Fortunately, based on physical evidence, an investigator can frequently determine how and why a structure failed. The most common reasons for a failure include defective materials, defective design, improper assembly, excessive or improper loading or a combination of these. Through testing and structural analysis, it is possible to determine the root cause of the failure and propose solutions to prevent such failures from reoccurring.

Construction sites and equipment present many hazards if proper care is not taken. The space in and around a construction site is often filled with potentially dangerous, high-powered equipment capable of delivering high forces.
Second only to automobile accidents, falls are the leading cause of injury and deaths. Of these, accidents due to slipping or tripping form a large proportion. Slips and trips occur on floors, streets, walkways, stairs, etc.
A warning must inform individuals of a danger, which would not be obvious to them. It must tell them how to avoid the danger, and be easily understood. It should also provide them with the consequences of not heading the warning.
