THE SPACE IN BETWEEN TWO AIR LOCKS PORTABLE
Traffic separation devices should be flexible and portable to allow for changing traffic patterns.ĭesign control points such that secure areas cannot be bypassed. Mechanical ductwork, piping, and main electrical conduit runs should not extend from one area to the other. A control desk and bag checking area should be located within the secure area. In higher-risk facilities, separate secure and non-secure areas with turnstiles, metal detectors, or other devices used to control access to secure areas. Provide ample high-contrast, large print directional signs throughout the lobby.Make information desks wheelchair accessible.Provide ramps and/or elevators as alternatives to stairs.Connect levels of the lobby via an accessible route of travel, or provide procedures to assist patrons with mobility impairments.Remove or minimize protruding objects for the safety of visually impaired users. Aisles kept wide and clear for wheelchair users.Doorway openings at least 32 inches wide and doorway thresholds no higher than 1/2 inch.Physical features to address in the lobby space include:
THE SPACE IN BETWEEN TWO AIR LOCKS HOW TO
Staff should also be educated and informed regarding how to provide an appropriate service or accommodation that might be requested or required.
Various types of disabilities should be considered, including those with visual, learning, mobility, speech, and hearing impairments. AccessibleĪccessibility should be planned early in the process. For a complete list and definitions of the design objectives within the context of whole building design, click on the titles below. Typical features of lobby space types include the list of applicable design objectives elements as outlined below. Key design concerns for this space type include balancing aesthetics, security, sustainability, and operational considerations. All conditioned, clean air supplied to the gown room is dissipated into the adjacent rooms while all the conditioned, clean air supplied to the airlock room (as well as all infiltration air into that room) is exhausted.The character and function of a lobby space often influence a visitor's first impression upon entering a building. This two-compartment airlock arrangement allows personnel to protect (gown/respirator) themselves before coming into contact with any dangerous materials while at the same time, the product (potent compound) is protected from contamination from adjacent, connected areas. The “potent compound airlock” is a combination of the pressure bubble and pressure sink airlocks. During a few types of production processes in a clean-room, air from a contaminated area has to be contained in one place. In many research facilities, substances that are experimented on are highly dangerous, and it is essential to keep them from being exposed. This airlock pulls air from both adjacent areas creating a low-pressure barrier and reduces the opportunity of contamination passing to the internal zone. Area such as higher potency, compounding areas terminal sterilization is not an option.Īirlocks having lower pressure inside the airlock and higher pressure on both sides of the airlock. Used in, areas where the product needs protection and the people external to the clean rooms require protection from the product, to reduce the possibility of viable articulate from entering the lesser pressure clean-room.
