latest revision seems too long and too wordy in my opinion. custom tailor the resume to meet whatever job you're applying for. if you're trying for a helpdesk/desktop job, you dont need all them details from anything nontechnical. [...] if the place you're applying for is a chemical plant for example, having the hazardous materials thing is beneficial. at a IT company, probably not so much.

keep like 4-5 different versions out there that you can quickly substitute relevant bullet points in based on the job you're applying to. make the helpdesk resume different than the desktop resume. then focus on making that resume show you know your stuff. a recruiter might spend 15 seconds in your resume. make it short, compact, and attention getting. The resume's goal is to get you into the interview where you can dazzle the interviewers with your skills.
Just my opinion 🙂
