hi everyone, the other day at work a fellow worker was spraying glyphosate diluted 300ml to 300l in a back pack sprayer, they were not using a breathing mask and the gloves they were wearing were the thin plastic disposable kind. i am after any reliable information and/or official studies that could give me enough info to make the boss re-think the way the company carries out chemical use. i'm young and i'm new to the job so i would like to have as many facts as possible. i've looked at the msds for the product and it seems to recommend ppe and breathing apparatis but i can't find a definate standard for safety. i know this isn't exactly permaculture related, i was just hoping to reduce the companies chemical use and provide info for the other employees. any help would be appreciated.
