These restrictions may lead to increased dangers. Renovation should not mar underlying supports which may consist of valuable wood or finishes. Barriers used to separate construction areas often must be free-standing units that cannot be attached to walls that have historic features. Rooflines or skyline restrictions in historic districts may pose serious challenges to construction of exhaust stacks with sufficient height. Exhaust ventilation system installations should not destroy historic facades. With historic buildings, the need to preserve historic integrity must be balanced against design requirements of life safety codes and accommodations for persons with disabilities. Lead paints, mercury linings on old mirrored surfaces and asbestos in decorative finishes and insulation are some examples. Renovation may lead to uncovering material hazards in both centuries-old buildings and modern ones. They often lack exterior wall vapour barriers and have air handling systems which are old and difficult to maintain.
Older buildings are prone to mould and mildew growth and poor indoor air quality. Custodial staff are exposed to splash hazards from diluting cleaning chemicals, chemical reactions from improperly mixed chemicals, dermatitis, inhalation hazards from dry sweeping of lead paint chips or residual preservative chemicals in collection storage areas, injury from broken laboratory glassware or working around sensitive laboratory chemicals and equipment, and biological hazards from cleaning building exteriors of bird debris. Health hazards include exposures to hazardous materials, noise, metal fumes, flux fumes and gases, and ultraviolet radiation and dermatitis from cutting oils, solvents, epoxies and plasticizers. Safety hazards include slips, trips and falls back and limb strains electrical shock and fires and explosions from compressed gas cylinders or hot work. General tasks involve custodians heating, ventilation and air-conditioning (HVAC) specialists and boiler engineers painters electricians plumbers welders and machinists. Fire prevention systems are critical to protect the lives of staff and a multitude of visitors, as well as the priceless collections. As buildings, museums are subject to poor indoor air quality and to risks associated with maintenance, repair, custodial and security activities of large public buildings. The operation of museums and galleries poses potential safety and health hazards both common to other occupations and unique to museums. Occupations, which may overlap depending on size of staff, include building maintenance trades and custodians, carpenters, curators, illustrators and artists, librarians and educators, scientific researchers, specialized shipping and receiving and security. Museums and galleries may be stand-alone entities or affiliated with larger institutions such as universities, government agencies, armed services installations, park service historic sites or even specific industries.Ī museum’s operations can be divided into several main functions: general building operations, exhibit and display production, educational activities, collection management (including field studies) and conservation. Collections on display generally represent a small fraction of the total acquisitions of the museum or gallery, with the remainder in on-site storage or on loan to other exhibits or research projects. Supportive research (fieldwork, literary and laboratory) and behind-the-scenes collection care typically represent the largest proportion of work activities. The broad mission of museums and art galleries is to collect, conserve, study and display items of artistic, historical, scientific or cultural importance. The exhibits, lectures and publications offered to the public by museums, however, are only one part of the function of museums. There are many different types of museums, such as art, history, science, natural history and children’s museums.
Museums and art galleries are a popular source of entertainment and education for the general public.
