Establishments typically without waiter/waitress service in which patrons generally order or select items and pay before consuming. I suspect (with you) that the plastic content may be less than the 25% by volume threshold (I believe there is a weight threshold too now), but even in this case the adjusted density hardly makes an impact on the project. While this gives a general idea of risk to large numbers of occupants, it was not descriptive and did not rank hazardous facilities with a high level of risk. Conventional primary activity and service codes, as with libraries, apply to specific areas. Compare the modified quantities with the planned inventory of each hazard class being used in the control area. Data Type: Constrained List Category: Premises Unit of Measure: None Sector: Commercial, Residential, Multifamily Term ID: Categorizing a chemical hazard is not difficult, but it may require some research using common reference sources, such as a safety data sheet (SDS).
