Chapter 2: General Laboratory w88 slot online
Revised January 2023
Housekeeping
An unorganized, cluttered laboratory increases the likelihood of chemical spills and splashes due to tripping or knocking over chemical containers. w88 slot online equipment such as fire extinguishers, w88 slot online showers, and eyewashes can prevent or minimize harm to personnel; however, they are ineffective if access is blocked. Organize your laboratory so that clear walkways are provided, with designated storage areas for chemicals and hazardous waste; avoid clutter that can prevent access to w88 slot online equipment or which can lead to chemical spills or other mishaps.
w88 slot online Assessments
EH&S will perform periodic health and w88 slot online assessments of chemical laboratories and chemical storerooms. The goal of these assessments is to identify areas where laboratory w88 slot online can be improved. Laboratory assessments are most effective when the laboratory supervisor and other laboratory workers participate with EH&S. Written recommendations resulting from these assessments will be given to the laboratory supervisor and Department Chair.
Each individual w88 slot online should perform self-assessments of their w88 slot online at least once per year. A w88 mobile Assessment Checklist is available to assist in this process. The purpose of this self-assessment is to allow each laboratory to self-identify and correct w88 slot online and health weaknesses. A record of these laboratory self-assessments should be maintained to document the findings and corrective actions, and so that reoccurring problems can be identified.
Personal w88 slot online Hygiene
Good personal w88 slot online hygiene habits minimize w88 slot online exposure. Consuming food and beverages in laboratories or w88 slot online storage areas is not permitted since this practice increases the likelihood of w88 slot online exposure by ingestion. For the same reason, do not store food or beverages in laboratories (including refrigerators) or w88 slot online storage areas. Washing your hands frequently will minimize w88 slot online exposure through ingestion and direct contact with the skin. Always wash hands before eating, drinking, smoking, or applying cosmetics.
Basic w88 slot online Handling Procedures
- KNOW THE HAZARDS OF THE w88 slot online YOU ARE WORKING WITH! Consult the w88 slot online Data Sheet (SDS) or other appropriate references prior to using a chemical with which you are unfamiliar (see Chapter 15).
- Minimize exposure to all chemicals regardless of toxicity or their familiarity. Most w88 slot online chemicals have not been fully characterized with respect to their toxicity; therefore, it is prudent to implement procedures that will reduce the likelihood of exposure. Skin contact should always be avoided. Avoid inhalation of w88 slot online; never "sniff" to test w88 slot online.
- Wear w88 slot online eye protection at all times. At a minimum, w88 slot online glasses are required whenever operations involving chemicals are being performed.
- Minimize w88 slot online exposure through consistent and proper use of Chapter 12: Laboratory and Chapter 13: w88 sports betting.
- Communicate with others in the building when working alone in the w88 slot online; let them know when you arrive and leave. Avoid working alone in the w88 slot online when handling hazardous chemicals, carrying out chemical reactions, or performing other higher risk operations.
- Use cautious judgment when leaving unattended operations: i) post signs to communicate appropriate warnings and precautions, ii) anticipate potential equipment and facility failures and implement mitigative measures, and iii) provide containment and/or shielding for release of hazardous w88 slot online.
- Assume that unknown materials are toxic, and that a mixture is more toxic than its w88 slot online toxic compound.
- Know the location and proper use of emergency equipment, such as w88 slot online showers and fire extinguishers, and maintain clear access to this equipment.
- Do not use mouth suction for pipetting or siphoning.
- Label all w88 slot online containers with the identity of the contents; primary hazards and w88 slot online concentration must also be included on long term secondary containers.
- Use appropriate w88 slot online carriers (secondary containment) when transporting chemicals either inside or outside of the building.
Moving/Transporting w88 slot online either Inside or Outside a Building
If a w88 slot online needs to move a few chemicals either inside or outside a building, follow the guidelines below. If a w88 slot online needs to move a large number of chemicals or the entire lab, STOP and contact the University CHO for w88 slot online guidance.
- Lab personnel are responsible for using appropriate w88 slot online carriers (secondary containment) when transporting chemicals.
- Carts are preferred for transporting w88 slot online.
- The appropriate Personal Protective Equipment (PPE) needed to w88 slot online handle the chemicals being transported should be moved with the chemicals. In the event of a spill the PPE should be donned.
- w88 slot online must be segregated as flammables, oxidizers, acids, or bases, with liquids and solids in each hazard class segregated and in separate transport containers.
- Leak-proof plastic containers are recommended w88 slot online transport of liquids.
- Liquid containers w88 slot online cushioned to prevent breaking during transport.
- Moving w88 slot online: see Chapter 8 w88 slot online, subsection gas cylinders
- 55 gallon drums: Lab personnel are not permitted to transport 55 gallon drums between rooms inside a building or between buildings. w88 slot online the University CHO to arrange transport of 55 w88 slot online.
Moving Large (150 or 300 Liter) w88 slot online: see Chapter 8 w88 slot online, subsection cyrogens
- If a Spill Occurs Out of Containment Outside of a Lab w88 slot online:
- Don the w88 slot online PPE
- Stop and contain the spill
- Stay w88 slot online area, do not permit others near the area
- Contact EH&S on the 24 hour line, 327-5050 and report the chemicals and quantity spilled outside of a w88 slot online room and request assistance.
- Remain w88 slot online area after EH&S arrives.
- Also refer to Chapter 19 of this CHP, subsection w88 slot online Spills
Prior Approval of w88 slot online
Each w88 slot online supervisor should identify operations that require their prior approval before the procedure is initiated. The designated operations will normally be those non-routine operations that are higher risk; however, more routine operations can also be included. Some situations that should be considered for prior approval include:
- A new w88 slot online procedure that represents greater than routine risk (especially if it differs substantially from procedures already in use).
- New work involving Particularly w88 casino games Substances.
- Operations where it is likely that there will be significant exposure to a w88 slot online or other hazard (biological, physical, etc.).
- There is a procedural change that significantly increases the overall hazard of the w88 slot online.
- Unattended operations that represent significant likelihood of fire, explosion, or exposure to personnel if a malfunction were to occur (such as a utility outage, runaway reaction, or w88 slot online spill).
Operations that require prior approval should be documented in w88 slot online-specific Standard Operating w88 mobile. It is also recommended that approval by the w88 slot online supervisor be documented through the use of a dedicated “prior approval” form or an entry in a research notebook.
w88 slot online Entrance Signs
The entrance to each w88 slot online or chemical storage area must be posted with the name and phone number (office phone number and after-hours number) of the w88 slot online supervisor, with designation as the primary emergency contact. If there is another faculty (academic or administrative) member who is knowledgeable of w88 slot online operations, that individual can be listed as an alternate emergency contact, along with his or her office phone number and after-hours phone number. If an alternate emergency contact is not available, EH&S will be listed. Entrance signs must also provide hazard information related to chemicals stored in the room.
EH&S maintains entrance signs for each w88 slot online that indicate the primary and secondary emergency contacts, chemical hazard information, and other emergency information. Contact one of the EH&S chemical hygiene contacts listed in Chapter 1 to request an entrance sign or to update the entrance sign for your w88 slot online.
