Lawo Best Practice Advice: Stay Safe On The Air


GER: Equipment manufacturer Lawo has provided some advice on 'Best Practices For Safe Cleaning of Broadcast Studios and Studio Equipment'

With the current coverage of unprecedented world events, many live and production studios are in use around the clock. Johns Hopkins warns that "Studies suggest that coronaviruses...may stay on surfaces for a few hours or up to several days" (1), so keeping common areas sanitized to protect on-air staff and production personnel is a top concern.

Just What the Doctor Ordered
Several measures for maintaining a clean work environment are recommended by the World Health Organization(2), Johns Hopkins, and the U. S. Centers for Disease Control and Prevention. First: hand-washing, with soap and water, for at least 20 seconds. Second: disinfecting communal areas like countertops, desks and other working spaces where the Covid-19 virus may be present. The CDC recommends "diluted household bleach solutions, alcohol solutions with at least 70% alcohol, and most common...household disinfectants should be effective." (3) They further recommend wearing disposable gloves when cleaning and disinfecting surfaces, and cleaning hands immediately after gloves are removed.

Do's and Don'ts
Before cleaning, remember that most broadcast equipment, Lawo products included, is made from a variety of different materials which could have adverse reactions to cleaning agents such as bleach and alcohol. Lawo recommends mild cleaning agents for sensitive broadcast gear; remember these "dos and don'ts" when cleaning audio equipment:
  • Unplug all external power sources before you clean the device.
  • Clean using a soft, slightly damp cloth, moistened lightly with warm to hot soapy water.
  • Don't use aerosol sprays, bleaches, or abrasives on broadcast equipment.
  • Don´t use any liquid cleaning agents or spray cleaners which may contain flammable materials.
  • Don't spray cleaning solution directly onto the item.
  • Be careful not to allow moisture into any openings.

Hands Off Alcohol!
Some cleaners may have effects so damaging that product warranties are affected. Please note the following cautions for specific Lawo products; Lawo cannot be held responsible for damage caused by using unapproved cleaning agents or disinfectants containing alcohol on these components.
  • VSM control panels using LCD buttons manufactured by NKK and e3. These products are not approved for treatment with chemical cleaning agents and disinfectants and can be permanently damaged by treatment with such agents.
  • Lawo Audio Production and Radio console surfaces are not approved for treatment with chemical cleaning agents and disinfectants. The use of some substances can even lead to permanent discoloration of work surfaces.
  • To be on the safe side wear disposable gloves whilst operating your broadcast equipment and sanitize your hands afterwards.
If you are in doubt about a cleaning agent you wish to use, contact your equipment's manufacturer first. Strong chemical cleaners and abrasives are to be avoided; a thorough cleaning with a cloth moistened with warm soapy water is enough to remove most contaminants from operating surfaces.
