Phase 1 – Pre-entry Procedures

Training:
All laboratory personnel and students will watch the return to campus video plus review safety and infection control procedures and any other guidelines or trainings session (provided by the EHS office)

Utilization of Teaching Laboratories A509, A511 and A308:
Laboratory spaces in A509, A511 and A308 will be the areas used for teaching courses CHEM3622, CHEM4312, CHEM 2323, and CHEM3312 in the Fall 2021. A509 will be the main space used for CHEM3622, CHEM 2323 and CHEM4312, whereas A308 will host CHEM3312. Laboratory A509 will operate at no more than 50% (12 students) of its maximum room capacity (24 students), plus the laboratory instructor. Lab A509 is 1,238 sq. ft. and houses 12 fume hoods with a separation of 3ft between them. Students will work individually using their own designated fume hood, which will allow to keep safe distancing (3ft.) with 50% occupancy. Additional equipment in laboratory A511 (825 sq. ft.) will be used as needed. No more than 3 students (25% capacity) will be in A511 at any given time, in order to maintain safe distancing. Likewise, laboratory A308 (1,206 sq. ft.) will operate at no more than 50% (12 students) of its maximum capacity (24 students). Laboratory A308 has two middle benches that are 19.5 ft. long and 4.5 ft. wide. No more than 3 students will use each side of a bench in a staggered manner to keep a safe 3ft distance with other students in all directions. Signs with maximum lab capacity will be posted on the doors of all three labs. Excess chairs in A308 and A511 will be removed (A509 has no chairs) and additional benches not in use will be taped. Signs will be posted in lab spaces A509, A511 and A308 to keep a record of lab utilization, as well as to instruct personnel and student to keep 3ft distance and to use face covers.

Prior to Coming to the Campus:
Pre-screening at home: each day before laboratory personnel and students reporting to campus, they will use Screening.NY.GOV to determine whether it is safe to report to the campus.

  • Laboratory instructors and students will answer the COVID daily health screening questions using the app Everbridge.

Campus/Building Entry:
Health Screening Guidelines: All laboratory personnel and students are required to complete the COVID pre-screening prior to coming to campus, using Everbridge. If asymptomatic and afebrile, they may come to campus.

  • The entrance of 285 Jay Street (Academic Building) will be the single designated entrance.
  • Only laboratory personnel with temperature lower than 100 degrees Fahrenheit and with appropriate face, covering will be permitted to enter the building and designated laboratory areas. Everbridge pre-approval will be required.
  • Access to the fifth floor can be via either escalator or elevators. Campus personnel will use the escalators with social distancing (3ft.) and disinfection of handrails every two hours.
  • Freight elevators will be designed to stop at each floor for handicap accessibility.
  • Upon arriving on the fifth floor, hand hygiene will be performed using the wall mounted Purell hand sanitizing liquid.
  • Faculty members and students will proceed to their assigned chemistry laboratory space.

In the Chemistry Teaching Areas (A509, A511 and A308)

  1. Social Distancing:
    • Social distancing will be maintained according to CDC and CUNY Guidelines.
    • Signs stating, “keep 3ft distance” will be posted in all three labs.
    • As social distancing is required, there will be a maximum of 12 students (plus instructor) in A509 and A308, or 3 students (plus instructor) in A511 on designated days.
    • Each student will be assigned a laboratory fume hood and lab bench and will maintain a social distance of 3ft from any personnel in the laboratory.
    • Lab benches will not be shared to maintain social distancing.
    • Laboratory instructors will remain by the instructor station and will only move to provide guidance always from 3ft or longer distance.
    • If an instrument demonstration is required, laboratory instructors will use the instrument, and students will remain at a safe distance in designated areas.
    • Common instruments will be used individually and disinfected after.
  2. Face Covering:
