| a\. A review is conducted by the supervisor (or cognizant      |   |   |
| individual) before the use of chemicals to determine the       |   |   |
| appropriate protective measures.                               |   |   |
+----------------------------------------------------------------+---+---+
| b\. Workers follow appropriate protective measures established |   |   |
| by their supervisor.                                           |   |   |
|                                                                |   |   |
| > 1\. Hoods, vents or other engineering controls are used as   |   |   |

| > are used as necessary. PPE is cleaned and stored properly.   |   |   |
+----------------------------------------------------------------+---+---+
| c\. Workers/management can demonstrate an appropriate          |   |   |
| criterion for PPE selection. *\[For example, how a particular  |   |   |
| type of glove is chosen. Appropriate sources of information    |   |   |
| include the MSDS, the CMS chemical hazard reference section    |   |   |
| ([www.esh.bnl.gov/cms](http://www.esh.bnl.gov/cms/)), or       |   |   |
| consultation with SHSD Facility Support Representative. Glove  |   |   |
| selection is based on the chemical resistance of the glove     |   |   |
| elastomer to a specific chemical. For selection assistance     |   |   |
| contact your ES&H Representative for further information.\]*   |   |   |
+----------------------------------------------------------------+---+---+
| d\. Employees and Supervisors understand the "Hierarchy of     |   |   |
| Controls." *(i.e., "Engineering controls" (hoods, ventilation, |   |   |
| guards, etc.) and "Substitution with a less hazardous          |   |   |
| chemical" are the method of choice when protecting workers.    |   |   |
| "Administrative Controls" (rotation of workers to limit        |   |   |
| exposure, shortening the exposure time per day, etc.) are next |   |   |
| in order of preference. Last choice is use of personal         |   |   |
| protective equipment.*)                                        |   |   |
+----------------------------------------------------------------+---+---+
| e\. Toxic chemicals, chemicals that have a high vapor          |   |   |
| pressure, and carcinogens are used in a hood.                  |   |   |
+----------------------------------------------------------------+---+---+
| f\. Yearly quantitative flow evaluations are done on           |   |   |
| laboratory fume hoods. *\[Consult ES&H Standard 2.2.1 and your |   |   |
| ES&H Representative for further guidance.\]*                   |   |   |
+----------------------------------------------------------------+---+---+
| g\. Lab hoods are used only with the sash height within posted |   |   |
| limits?                                                        |   |   |
+----------------------------------------------------------------+---+---+
| **4. Chemical Labeling**                                       |   |   |

| of this move?*\]                                               |   |   |
+----------------------------------------------------------------+---+---+
| d\. At disposal of chemicals, bar codes are forwarded to the   |   |   |
| CMS staff for deletion of chemicals from the inventory. \[*Is  |   |   |
| the Inventory maintained current by sending depleted chemical  |   |   |
| container bar-codes back to the CMS Team for deletion?*        |   |   |
| *Experimenters who leave BNL are responsible for the           |   |   |
| identification and disposal of chemicals before their          |   |   |
| departure. All CMS records must be reconciled before           |   |   |
| departure.\]*                                                  |   |   |
+----------------------------------------------------------------+---+---+
| e\. If a chemical container is brought on site through         |   |   |
| non-standard purchasing methods, the chemical container must   |   |   |
