Viability of using masks while debating

I AM writing to raise concerns regarding the health and safety of our Parliamentarians who will be sitting for the one-day meeting on May 18. I have written about my concerns over the distancing of the seats before, and I now wish to raise some questions about the health of our lawmakers if they are forced to wear the medical masks for four to eight hours. I assume that when Parliament meets again in July, MPs would still be required to wear masks.

Will it be safe for someone like Tun Dr Mahathir Mohamad or those above 70 years and those having respiratory issues if they make long speeches in a heated debate while wearing the face masks? I am raising this issue because of the disturbing report on the death of three teenagers in China while doing physical exercise with masks on. There is also the report of a 26-year-old jogger in Wuhan who suffered a punctured lung while jogging for 5km.
