Safety and Gantt Charts

1. Safety and Gantt Charts ChE 477 (UO Lab) Lecture 2 Larry Baxter & William Hecker Brigham Young University

2. Outline • Lab safety. • General location of fire pulls (building exits). • Fire extinguisher types and locations (four in lab). • Safety standards organizations (ANSI, NFPA, etc.). • Gantt charts. • Project management triangle. • Gantt charts. • Microsoft project.

3. MSDS Sheets • Written differently by different companies but should have similar information. • Generally conservative. • Often need interpretation by qualified professionals (you).

4. Origins of Safety Rules • Desire to protect yourself and colleagues from undue hazards. • Legal requirements. • Threats of lawsuits.

5. The Origin of Safety Standards • Congress writes laws. • The executive (President and, in this case, Department of Labor’s Occupational Safety and Health Administration - OSHA) develop regulations. • Non-government organizations develop standards. • Courts (commonly) adjudicate differences.

6. OSHA Laws/Regulations • OSHA regulations (standards - 29 CFR). • Eye and face protection. - 1910.133. • (A). • General requirements. • (A)(1). • The employer shall ensure that each affected employee uses appropriate eye or face protection when exposed to eye or face hazards from flying particles, molten metal, liquid chemicals, acids or caustic liquids, chemical gases or vapors, or potentially injurious light radiation.

7. OSHA Regulations (Cont’d) • (A)(2). • The employer shall ensure that each affected employee uses eye protection that provides side protection when there is a hazard from flying objects. Detachable side protectors (e.G. Clip-on or slide-on side shields) meeting the pertinent requirements of this section are acceptable.

8. OSHA Regulations (Cont’d) • The employer shall ensure that each affected employee who wears prescription lenses while engaged in operations that involve eye hazards wears eye protection that incorporates the prescription in its design, or wears eye protection that can be worn over the prescription lenses without disturbing the proper position of the prescription lenses or the protective lenses. • (A)(4). • Eye and face PPE shall be distinctly marked to facilitate identification of the manufacturer.

9. OSHA Regulations (Cont’d) • (B). • Criteria for protective eye and face devices. • (B)(1). • Protective eye and face devices purchased after July 5, 1994 shall comply with ANSI Z87.1-1989, "American national standard practice for occupational and educational eye and face protection," which is incorporated by reference as specified in sec. 1910.6. • (B)(2). • Eye and face protective devices purchased before July 5, 1994 shall comply with the ANSI "USA standard for occupational and educational eye and face protection," Z87.1-1968, which is incorporated by reference as specified in sec. 1910.6, or shall be demonstrated by the employer to be equally effective.

10. Standards Organization • American national standards institute (ANSI). • Safety glasses is standard Z87. • Many other safety and non-safety related standards. • National fire protection association (NFPA). • Most fire-related standards. • National electric code (NEC).

11. Standards Organization (Cont’d) • Standards organizations are generally not government agencies and do not write laws or regulations. • Standards acquire regulatory importance when cited in contracts or regulations/laws.

12. Project Organization • Objective. • Complete project safely, on time, within budget, and within specifications. • Foresee project’s future.

13. Project Management Triangle • Time • Resources • Budget • People • Facilities • Specifications • Scope • Requirements Time Resources Specifications

14. Steps to Manage Project • Analyze project • Divide task into units • Establish relationships between units • Schedule units beginning as early as possible • Adjust schedule to meet deadlines and constraints
