Protective enclosures are structures designed to safeguard sensitive equipment or materials from environmental hazards, physical damage, or unauthorized access. Commonly used in various industries, these enclosures can be made from materials like metal, plastic, or glass, depending on the level of protection required. They are essential for maintaining the integrity of items such as electronics, chemicals, or biological samples. These enclosures can vary in complexity, from simple boxes to sophisticated systems with climate control and security features. Examples include electrical cabinets, safety cages, and laboratory fume hoods. Proper design and installation of protective enclosures help ensure safety and compliance with industry regulations.
