does Oregon OSHA do? • Our mission is to improve workplace safety and health for Oregon workers • Our program includes consultation and enforcement – Consultations are no-cost, confidential consultations requested by employers that could include hazard assessments and recommendations – Enforcement involves inspections not requested by employers (i.e., program planned inspections, complaints, accidents) and can issue citations and penalties. ~n LOStiA

Why is Oregon OSHA here? • The Lincoln County School District asked Oregon OSHA for a consultation involving Crestview Heights Elementary School • The district's request stemmed from its concern about an indoor air quality issue regarding potential diesel exhaust • The district waived its right to confidentiality, allowing us to present our consultation report's findings to the public and to answer questions ~n LOStiA

What are Oregon OSHA's findings? • Air monitoring for carbon monoxide, carbon dioxide, oxygen, nitrogen dioxide, sulfur dioxide, formaldehyde, hydrogen sulfide, methane, volatile organic compounds (VOCs), diesel particulate matter, and fine particles was conducted April 25, 2019 through April 26, 2019. • The air monitoring captured ambient levels prior to the boilers being started up, during the boilers' startup and continued to monitor the ambient air inside the elementary school during normal operation of the boilers as well as the stack analysis performed by the boiler inspector. ~n LOStiA
