◍ What three systems are included under this standard?.
, Answer: Medical vacuum system support suction equipment, and evacuation
procedures, a medical vacuum system does not carry, biological matter and
is classified as a dry system however, it could still carry airborne biological
hazardsA dental vacuum system, which is a wet system and carries
biological materials. A dental vacuum system must never be connected to a
medical vacuum system. An anaesthetic gas scavenging system AGSS is
using hospital anaesthesia evacuation procedures
