Required Qualifications
• Education: Bachelor's degree in EHS, Chemical Engineering, Industrial 
Hygiene, Occupational Safety, or a related science/engineering field.
• Experience: Minimum of 3-5 years of progressive EHS experience, 
specifically in a chemical processing/manufacturing or semiconductor 
fabrication environment.
• Knowledge:
o Strong working knowledge of US federal (OSHA, EPA) and state EHS 
regulations, or equivalent international standards.
o In-depth understanding of PSM/RMP regulations and implementation.
o Familiarity with cleanroom protocols and safety requirements for 
hazardous production materials (HPMs), particularly silane, 
phosphine, arsine, and other gases used in semiconductor processing.
o Experience with chemical compatibility, storage, and transfer 

Key Responsibilities
1. Compliance and Regulatory Management
• Develop, implement, and maintain site-specific EHS programs, policies, and 
procedures in accordance with local, state, federal, and international EHS 
regulations (e.g., OSHA, EPA, ISO 14001, ISO 45001).
• Ensure compliance with Process Safety Management (PSM) and Risk 
Management Plan (RMP) standards for hazardous chemicals common in 
both the chemical industry and semiconductor fabrication (e.g., highly toxic 
gases, flammable liquids, strong acids/bases).
• Prepare and submit all required EHS permits, reports, and documentation
to regulatory agencies.
• Conduct internal and external audits to assess compliance status and drive 
continuous improvement.
2. Risk Assessment and Hazard Control
• Perform Job Hazard Analyses (JHA), risk assessments, and ergonomic 
evaluations for all manufacturing, laboratory, and maintenance activities.
Shutterstock
• Implement and manage controls for site hazards, including industrial hygiene 
monitoring (e.g., noise, air contaminants, chemical exposure), Lockout/
Tagout (LOTO), confined space entry, and hot work.
• Develop and manage the site's emergency response plan for incidents such as 
chemical spills, fires, and medical emergencies, and coordinate necessary 
drills and training.
• Manage the selection, inspection, and maintenance of Personal Protective 
Equipment (PPE), ensuring specific requirements are met for cleanroom 
environments and chemical handling areas.
3. Environmental Stewardship
• Oversee waste management programs, including the safe handling, storage, 
and disposal of hazardous and non-hazardous waste, with a focus on chemical 
waste streams unique to the industries.
• Manage air emissions permitting and monitoring, including volatile organic 
compounds (VOCs) and hazardous air pollutants (HAPs).
• Ensure compliance with wastewater discharge permits and monitor 
pretreatment systems specific to metal and chemical waste.
• Implement and track sustainability and resource conservation initiatives
(e.g., water and energy reduction).
4. Training and Culture
• Develop and deliver mandatory EHS training programs for all employees, 
contractors, and visitors, including new hire safety orientation and recurring 
specialized training (e.g., chemical handling, cleanroom safety, emergency 
procedures).
• Lead and champion the site's EHS culture, promoting employee 
involvement, accountability, and hazard identification.
5. Incident Management
• Lead incident investigations (accidents, near misses, chemical releases) to 
determine root causes using established methodologies (e.g., TapRooT, 5 
Whys).
• Develop and track corrective and preventive actions (CAPAs) to prevent 
recurrence.
• Manage workers' compensation claims and return-to-work programs in 
collaboration with Human Resources.
6. Conduct Safety Improvement Project 
• Plan & execute safety improvement project in case of needed.
