is this a poisonous snake?

Last night my friend sent a ficture of a snake found on a nursery tree Jernang near his home. But me do not know what the name of the snake is and whether it is a kind of poisonous snake.

Here I can only suggest that we remain cautious when dismantling plant seeds at night, snakes can just stay in unexpected places. May we avoid the poisonous snake's snare?. thanks @ismuel
