Safety Program |

|
|||
Jefferson Lab has determined that working with silica carries an unmitigated Risk Code >2. At a minimum all tasks involving silica are discussed with the supervisor prior to commencement. An Operational Safety Procedure (OSP) is written for any work considered to be Risk Code >2 in accordance with ES&H Manual Chapter 3210 Work Planning, Control, and Authorization Process. |
1.0
Purpose
Silica, when dispersed in air (dust particulates), poses a serious health hazard. This program addresses techniques for mitigating silica exposure for activities that occurs at Jefferson Lab including, but not limited to grinding, cutting, mixing, and drilling of concrete, brick, grout, and rock; miscellaneous sand and gravel operations; and removal of furnace insulation[1].
This program satisfies applicable federal, state, and local requirements as outlined in ES&H Manual Chapter 2410 Appendix T1 Hazard Issues List.
2.0
Scope
For the purposes of this program “silica” refers to respirable
crystalline, quartz, cristobalite, and tridymite. Contact Industrial Hygiene for guidance when
using other forms.
This program applies to activities at Jefferson Lab
that would commonly occur during day-to-day operations. This program complies with requirements of 29 CFR 1910.1053 and 29 CFR
1926.115.
Other silica mitigation techniques, utilized for larger projects, may be considered during a Jefferson Lab facility design or modification review. Refer to ES&H Manual Chapter 3110 Facility Design and Modification Review.

Depending on the complexity of the activity (i.e. indoors, confined space), Industrial Hygiene may require "hold points" to verify control adequacy of engineered, administrative controls, and/or Personal Protective Equipment (PPE). Involve Jefferson Lab Industrial Hygiene in work planning activities.

3.2 Supervisor/Technical Representative (TR)/Sponsor:
· Provide a complete Work Plan in accordance with process steps.
· Assign only Trained Workers to silica work.
3.2.1 TR also:
· Inform subcontractors that their Activity Hazard Analysis (AHA) must include the planned technique(s) to mitigate silica exposure and the program used to train workers.
· If provided, submit subcontractor’s silica AHA to Jefferson Lab’s Silica Subject Matter Expert (see ES&H Manual Chapter 2410 Appendix T1 Hazard Issues List – Silica) for approval prior to commencement of work.
· Perform silica work/area hazard evaluation as appropriate.
3.4
Silica
Subject Matter Expert (SME)
· Oversee the onsite silica training program.
· Review and evaluate the effectiveness of the program at least annually and update it as necessary.
· Make silica equivalent training determination for Subcontractor Programs.
· Maintain listing of Trained Workers in accordance with ES&H Manual Chapter 4200 ES&H Training Overview.

Furnace insulation (refractory ceramic
fibers/synthetic vitreous fibers (RCF/SVF)) when exposed for long periods at
high temperatures (1100C/1900F) convert to a form of silica and must be
properly controlled. Contact Industrial
Hygiene for detailed mitigation requirements.
